[h4 Math-2.5.1 (Boost-1.63)]
|
|
|
|
Patches:
|
|
|
|
* Fixed evaluation of zero polynomial in polynomial.hpp, see [@https://svn.boost.org/trac/boost/ticket/12532 12532].
|
|
* Fixed missing header include in boost/math/tools/tuple.hpp, see [@https://svn.boost.org/trac/boost/ticket/12537 12537].
|
|
|
|
[h4 Math-2.5.0 (Boost-1.62)]
|
|
|
|
New Features:
|
|
|
|
* Enabled all the special function code to work correctly with types whose precision can change at runtime: for example type `mpfr_float` from Boost.Multiprecision.
|
|
|
|
Patches:
|
|
|
|
* Fix tgamma_delta_ratio for cases where the delta is small compared to the base.
|
|
* Fix misc GCC-4.4 test failures.
|
|
|
|
[h4 Math-2.4.0 (Boost-1.61)]
|
|
|
|
New Features:
|
|
|
|
* Polynomial arithmetic added to tools.
|
|
|
|
|
|
[h4 Math-2.3.0 (Boost-1.60)]
|
|
|
|
New Features:
|
|
|
|
* Promote the root finding and function minimization code to first class citizens - these are now officially supported as part of the library.
|
|
* Allow the library to be used and tested with compiler exception handling support turned off. To better facilitate this
|
|
the default error handling policies have been changed to ['errno_on_error] but only when the compiler has no exception handling support.
|
|
|
|
Patches:
|
|
|
|
* Fix behaviour of the non-central chi-squared distribution when the non-centrality parameter is zero to match the chi-squared,
|
|
see [@https://svn.boost.org/trac/boost/ticket/11557 11557].
|
|
* Fix comments in code for the hypergeometric to match what it actually does, also fixes the parameter access functions to return
|
|
the correct values. See [@https://svn.boost.org/trac/boost/ticket/11556 11556].
|
|
* Stopped using hidden visiblity library build with the Oracle compiler as it leads to unresolved externals from the C++ standard library.
|
|
See [@https://svn.boost.org/trac/boost/ticket/11547 11547].
|
|
* Fix unintended use of __declspec when building with Oracle C++. See [@https://svn.boost.org/trac/boost/ticket/11546 11546].
|
|
* Fix corner case bug in root bracketing code, see [@https://svn.boost.org/trac/boost/ticket/11532 11532].
|
|
* Add some missing typecasts in arguments to std::max in Bernoulli code. See [@https://svn.boost.org/trac/boost/ticket/11453 11453].
|
|
* Fix mistaken assumptions about the possible values for FLT_EVAL_METHOD. See [@https://svn.boost.org/trac/boost/ticket/11429 11429].
|
|
* Completely revamped performance testing and error-rate measuring code so we can more easily document how well (or not!) we're doing.
|
|
This information will hopefully get more frequently updated in future as it's more or less automatically generated - see the /reporting/
|
|
sub-directory for more information.
|
|
* Fix some corner cases in the beta, incomplete beta, and incomplete beta derivative. With thanks to Rocco Romeo.
|
|
* Reorganized the Bessel functions internally to improve the performance of Jn and Yn.
|
|
* Fixed skewness formula for triangular distribution, see [@https://svn.boost.org/trac/boost/ticket/11768 #11768].
|
|
* Fixed some examples so they compile on Unix platforms which have an ::exception struct declared, see [@https://svn.boost.org/trac/boost/ticket/11827 #11827].
|
|
* Correct mistake in triangular distribution skewness formula [@https://svn.boost.org/trac/boost/ticket/11768 11768],
|
|
reported by Juan Leni.
|
|
|
|
[h4 Math-2.2.1]
|
|
|
|
Patch release for Boost-1.58:
|
|
|
|
* Minor [@https://github.com/boostorg/math/pull/13#issuecomment-98905579 patch for Haiku support.]
|
|
* Fix the decimal digit count for 128-bit floating point types.
|
|
* Fix a few documentation typos.
|
|
|
|
[h4 Math-2.2.0 (boost-1.58.0)]
|
|
|
|
* Added two new special functions - __trigamma and __polygamma.
|
|
* Fixed namespace scope constants so they are constexpr on conforming compilers, see https://svn.boost.org/trac/boost/ticket/10901.
|
|
* Fixed various cases of spurious under/overflow in the incomplete beta and gamma functions, plus the elliptic integrals,
|
|
with thanks to Rocco Romeo.
|
|
* Fix 3-arg __legendre_p and __legendre_q functions to not call the policy based overload if the final argument
|
|
is not actually a policy.
|
|
* Cleaned up some dead code in the incomplete beta function, see [@https://svn.boost.org/trac/boost/ticket/10985 #10985].
|
|
* Fixed extreme-value pdf for large valued inputs, see [@https://svn.boost.org/trac/boost/ticket/10938 #10938].
|
|
* Large update to the Elliptic integral code to use Carlson's latest algorithms - these should be more stable, more accurate
|
|
and slightly faster than before. Also added support for Carlson's RG integral.
|
|
* Added __ellint_d, __jacobi_zeta and __heuman_lambda elliptic integrals.
|
|
* Switched documentation to use SVG rather than PNG graphs and equations - browsers seem to have finally caught up!
|
|
|
|
[h4 Math-2.1.0 (boost-1.57.0)]
|
|
|
|
* Added __hyperexponential_distrib.
|
|
* Fix some spurious overflows in the incomplete gamma functions (with thanks to Rocco Romeo).
|
|
* Fix bug in derivative of incomplete beta when a = b = 0.5 - this also effects several non-central distributions,
|
|
see [@https://svn.boost.org/trac/boost/ticket/10480 10480].
|
|
* Fixed some corner cases in __round.
|
|
* Don't support 80-bit floats in cstdfloat.hpp if standard library support is broken.
|
|
|
|
[h4 Math-2.0.0 (Boost-1.56.0)]
|
|
|
|
* [*Breaking change]: moved a number of non-core headers that are predominantly used for internal
|
|
maintenance into `libs/math/include_private`. The headers effected are `boost/math/tools/test_data.hpp`,
|
|
`boost/math/tools/remez.hpp`, `boost/math/constants/generate.hpp`, `boost/math/tools/solve.hpp`,
|
|
`boost/math/tools/test.hpp`.
|
|
You can continue to use these headers by adding `libs/math/include_private` to your compiler's include path.
|
|
* [*Breaking change]: A number of distributions and special functions were returning the maximum finite value
|
|
rather than raising an __overflow_error, this has now been fixed, which means these functions now behave as
|
|
documented. However, since the default behavior on raising an __overflow_error is to throw a `std::overflow_error`
|
|
exception, applications which have come to reply rely on these functions not throwing may experience exceptions
|
|
where they did not before. The special functions involved are __gamma_p_inva, __gamma_q_inva,
|
|
__ibeta_inva, __ibetac_inva, __ibeta_invb, __ibetac_invb, __gamma_p_inv, __gamma_q_inv. The distributions
|
|
involved are __pareto_distrib, __beta_distrib, __geometric_distrib, __negative_binomial_distrib,
|
|
__binomial_distrib, __chi_squared_distrib, __gamma_distrib, __inverse_chi_squared_distrib,
|
|
__inverse_gamma_distrib. See [@https://svn.boost.org/trac/boost/ticket/10111 #10111].
|
|
* Fix __round and __trunc functions so they can be used with integer arguments, see [@https://svn.boost.org/trac/boost/ticket/10066 #10066].
|
|
* Fix Halley iteration to handle zero derivative (with non-zero second derivative), see [@https://svn.boost.org/trac/boost/ticket/10046 #10046].
|
|
|
|
[h4 Math-1.9.1]
|
|
|
|
* Fix Geometric distribution use of Policies, see [@https://svn.boost.org/trac/boost/ticket/9833 #9833].
|
|
* Fix corner cases in the negative binomial distribution, see [@https://svn.boost.org/trac/boost/ticket/9834 #9834].
|
|
* Fix compilation failures on Mac OS.
|
|
|
|
[h4 Math-1.9.0]
|
|
|
|
* Changed version number to new Boost.Math specific version now that we're in the modular Boost world.
|
|
* Added __bernoulli_numbers, changed arbitrary precision __tgamma/__lgamma to use Sterling's approximation (from Nikhar Agrawal).
|
|
* Added first derivatives of the Bessel functions: __cyl_bessel_j_prime, __cyl_neumann_prime, __cyl_bessel_i_prime, __cyl_bessel_k_prime, __sph_bessel_prime and __sph_neumann_prime (from Anton Bikineev).
|
|
* Fixed buggy Student's t example code, along with docs for testing sample means for equivalence.
|
|
* Documented `max_iter` parameter in root finding code better, see [@https://svn.boost.org/trac/boost/ticket/9225 #9225].
|
|
* Add option to explicitly enable/disable use of __float128 in constants code, see [@https://svn.boost.org/trac/boost/ticket/9240 #9240].
|
|
* Cleaned up handling of negative values in Bessel I0 and I1 code (removed dead code), see [@https://svn.boost.org/trac/boost/ticket/9512 #9512].
|
|
* Fixed handling of very small values passed to __tgamma and __lgamma so they don't generate spurious overflows (thanks to Rocco Romeo).
|
|
* [@https://svn.boost.org/trac/boost/ticket/9672 #9672 PDF and CDF of a Laplace distribution throwing domain_error]
|
|
Random variate can now be infinite.
|
|
* Fixed several corner cases in __rising_factorial, __falling_factorial and __tgamma_delta_ratio with thanks to Rocco Romeo.
|
|
* Fixed several corner cases in __rising_factorial, __falling_factorial and __tgamma_delta_ratio (thanks to Rocco Romeo).
|
|
* Removed constant `pow23_four_minus_pi ` whose value did not match the name (and was unused by Boost.Math), see
|
|
[@https://svn.boost.org/trac/boost/ticket/9712 #9712].
|
|
|
|
[h4 Boost-1.55]
|
|
|
|
* Suppress numerous warnings (mostly from GCC-4.8 and MSVC) [@https://svn.boost.org/trac/boost/ticket/8384 #8384], [@https://svn.boost.org/trac/boost/ticket/8855 #8855],
|

|
|
* Fixed Student's T distribution to behave correctly with huge degrees of freedom (larger than the largest representable integer) [@https://svn.boost.org/trac/boost/ticket/8837 #8837].
|
|
* Make some core functions usable with `long double` even when the platform has no standard library `long double` support [@https://svn.boost.org/trac/boost/ticket/8940 #8940].
|
|
* Fix error handling of distributions to catch invalid scale and location parameters when the random variable is infinite [@https://svn.boost.org/trac/boost/ticket/9042 #9042] and [@https://svn.boost.org/trac/boost/ticket/9126 #9126].
|

|
|
[@http://discovery.ucl.ac.uk/1463470/ Efficient and Accurate Parallel Inversion of the Gamma Distribution, Thomas Luu]
|
|
[h4 Boost-1.54]
|
|
|
|
* Major reorganization to incorporate other Boost.Math like Integer Utilities Integer Utilities (Greatest Common Divisor and Least Common Multiple), quaternions and octonions.
|
|
Making new chapter headings.
|
|
* Added many references to Boost.Multiprecision and `cpp_dec_float_50` as an example of a User-defined Type (UDT).
|
|
* Added Clang to list of supported compilers.
|
|
* Fixed constants to use a thread-safe cache of computed values when used at arbitrary precision.
|
|

|
where the derivative is flatlining. Example is computing the quantile of the Fisher F distribution for probabilities
|
|
smaller than machine epsilon. See ticket [@https://svn.boost.org/trac/boost/ticket/8314 #8314].
|
|
|
|
[h4 Boost-1.53]
|
|
|
|
* Fixed issues [@https://svn.boost.org/trac/boost/ticket/7325 #7325], [@https://svn.boost.org/trac/boost/ticket/7415 #7415]
|
|
and [@https://svn.boost.org/trac/boost/ticket/7416 #7416], [@https://svn.boost.org/trac/boost/ticket/7183 #7183],
|
|
[@https://svn.boost.org/trac/boost/ticket/7649 #7649], [@https://svn.boost.org/trac/boost/ticket/7694 #7694],

|
|
[@https://svn.boost.org/trac/boost/ticket/7891 #7891], [@https://svn.boost.org/trac/boost/ticket/7429 #7429].
|
|
* Fixed mistake in calculating pooled standard deviation in two-sample students t example
|
|
[@https://svn.boost.org/trac/boost/ticket/7402 #7402].
|
|
* Improve complex acos/asin/atan, see [@https://svn.boost.org/trac/boost/ticket/7290 #7290],
|

|
|
|
|
[h4 Boost-1.52]
|
|
|
|
* Corrected moments for small degrees of freedom [@https://svn.boost.org/trac/boost/ticket/7177 #7177] (reported by Thomas Mang).
|
|
* Added [link math_toolkit.airy Airy functions] and [link math_toolkit.jacobi Jacobi Elliptic functions].
|
|
* Corrected failure to detect bad parameters in many distributions
|
|
[@https://svn.boost.org/trac/boost/ticket/6934 #6934] (reported by Florian Schoppmann)
|
|
by adding a function check_out_of_range to test many possible bad parameters.
|
|
This test revealed several distributions where the checks for bad parameters were ineffective,
|
|
and these have been rectified.
|
|
* Fixed issue in Hankel functions that causes incorrect values to be returned for ['x < 0] and [nu] odd, see [@https://svn.boost.org/trac/boost/ticket/7135 #7135].
|
|
* Fixed issues [@https://svn.boost.org/trac/boost/ticket/6517 #6517], [@https://svn.boost.org/trac/boost/ticket/6362 #6362],
|
|
[@https://svn.boost.org/trac/boost/ticket/7053 #7053], [@https://svn.boost.org/trac/boost/ticket/2693 #2693],
|
|
[@https://svn.boost.org/trac/boost/ticket/6937 #6937], [@https://svn.boost.org/trac/boost/ticket/7099 #7099].
|
|
|
|
|
|
* Permitted infinite degrees of freedom [@https://svn.boost.org/trac/boost/ticket/7259 #7259]
|
|
implemented using the normal distribution (requested by Thomas Mang).
|
|
* Much enhanced accuracy for large degrees of freedom [nu] and/or large non-centrality [delta]
|
|
by switching to use the Students t distribution
|
|
(or Normal distribution for infinite degrees of freedom)
|
|
centered at delta,
|
|
when [delta] / (4 * [nu]) < epsilon for the floating-point type in use.
|
|
[@https://svn.boost.org/trac/boost/ticket/7259 #7259].
|
|
It was found that the incomplete beta was suffering from serious cancellation errors
|
|
when degrees of freedom was very large. (That has now been fixed in our code,
|
|
but any code based on Didonato and Morris's original papers
|
|
(probably every implementation out there actually) will have the same issue).
|
|
|
|
[h4 Boost-1.51]
|
|
See Boost-1.52 - some items were added but not listed in time for the release.
|
|
|
|
[h4 Boost-1.50]
|
|
|
|
* Promoted math constants to be 1st class citizens,
|
|
including convenient access to the most widely used
|
|
built-in float, double, long double via three namespaces.
|
|
* Added the Owen's T function and Skew Normal distribution written by Benjamin Sobotta: see __owens_t and skew_normal_distrib.
|
|
* Added Hankel functions __cyl_hankel_1, __cyl_hankel_2, __sph_hankel_1 and __sph_hankel_2.
|
|
* Corrected issue [@https://svn.boost.org/trac/boost/ticket/6627 #6627 nonfinite_num_put formatting of 0.0 is incorrect]
|
|
based on a patch submitted by K R Walker.
|
|
* Changed constant initialization mechanism so that it is thread safe even for user-defined types, also
|
|
so that user defined types get the full precision of the constant, even when `long double` does not.
|
|
So for example 128-bit rational approximations will work with UDT's and do the right thing, even though
|
|
`long double` may be only 64 or 80 bits.
|
|
* Fixed issue in `bessel_jy` which causes Y[sub 8.5](4[pi]) to yield a NaN.
|
|
|
|
[h4 Boost-1.49]
|
|
|
|
* Deprecated wrongly named `twothirds` math constant in favour of `two_thirds` (with underscore separator).
|
|
(issue [@https://svn.boost.org/trac/boost/ticket/6199 #6199]).
|
|
* Refactored test data and some special function code to improve support for arbitary precision and/or expression-template-enabled types.
|
|
* Added new faster zeta function evaluation method.
|
|
|
|
Fixed issues:
|
|
|
|
* Corrected CDF complement for Laplace distribution (issue [@https://svn.boost.org/trac/boost/ticket/6151 #6151]).
|
|
* Corrected branch cuts on the complex inverse trig functions, to handle signed zeros (issue [@https://svn.boost.org/trac/boost/ticket/6171 #6171]).
|
|
* Fixed bug in `bessel_yn` which caused incorrect overflow errors to be raised for negative ['n] (issue [@https://svn.boost.org/trac/boost/ticket/6367 #6367]).
|
|
* Also fixed minor/cosmetic/configuration issues [@https://svn.boost.org/trac/boost/ticket/6120 #6120], [@https://svn.boost.org/trac/boost/ticket/6191 #6191],
|
|

|
|
[h4 Boost-1.48]
|
|
|
|
* Added new series evaluation methods to the cyclic Bessel I, J, K and Y functions.
|

|
|
|
|
* Corrected wrong out-of-bound uniform distribution CDF complement values [@https://svn.boost.org/trac/boost/ticket/5733 #5733].
|
|
|
|
* Enabled long double support on OpenBSD (issue [@https://svn.boost.org/trac/boost/ticket/6014 #6014]).
|
|
|
|
* Changed nextafter and related functions to behave in the same way as other implementations - so that nextafter(+INF, 0)
|
|
is a finite value (issue [@https://svn.boost.org/trac/boost/ticket/5823 #5832]).
|
|
|
|
* Changed tuple include configuration to fix issue when using in conjunction with Boost.Tr1 (issue [@https://svn.boost.org/trac/boost/ticket/5934 #5934]).
|
|
|

|
|
* Fixed missing std:: prefix in nonfinite_num_facets.hpp (issue [@https://svn.boost.org/trac/boost/ticket/5914 #5914]).
|
|
|
|
* Minor patches for Cray compiler compatibility.
|
|
|
|
[h4 Boost-1.47]
|
|
|
|
* Added changesign function to sign.hpp to facilitate addition of nonfinite facets.
|
|
* Addition of nonfinite facets from Johan Rade, with tests,
|
|
examples of use for C99 format infinity and NaN, and documentation.
|
|
* Added tests and documentation of changesign from Johan Rade.
|
|
|

|
Chi Square Distribution when [nu] = 3, see bug report [@https://svn.boost.org/trac/boost/ticket/2877 #2877].
|
|
* Fixed minor bugs [@https://svn.boost.org/trac/boost/ticket/2873 #2873].

|
[h4 Boost-1.35.0: Post Review First Official Release]
|
|
|
|
* Added Policy based framework that allows fine grained control
|
|
over function behaviour.
|
|
* [*Breaking change:] Changed default behaviour for domain, pole and overflow errors
|
|
to throw an exception (based on review feedback), this
|
|
behaviour can be customised using __Policy's.
|
|
* [*Breaking change:] Changed exception thrown when an internal evaluation error
|
|
occurs to boost::math::evaluation_error.
|
|
* [*Breaking change:] Changed discrete quantiles to return an integer result:
|
|
this is anything up to 20 times faster than finding the true root, this
|
|
behaviour can be customised using __Policy's.
|
|
* Polynomial/rational function evaluation is now customisable and hopefully
|
|
faster than before.
|
|
* Added performance test program.
|
|
|
|
[h4 Milestone 4: Second Review Candidate (1st March 2007)]
|
|
|
|
* Moved Xiaogang Zhang's Bessel Functions code into the library,
|
|
and brought them into line with the rest of the code.
|
|
* Added C# "Distribution Explorer" demo application.
|
|
|
|
[h4 Milestone 3: First Review Candidate (31st Dec 2006)]

* Implemented the Hermite, Legendre and Laguerre polynomials plus the
|
|
spherical harmonic functions from TR1.
|
|
* Moved Xiaogang Zhang's elliptic integral code into the library,
|
|
and brought them into line with the rest of the code.
|
|
* Moved Hubert Holin's existing Boost.Math special functions
|
|
into this library and brought them into line with the rest of the code.
|
|
|
|
[h4 Milestone 2: Released September 10th 2006]

|
|
* Implemented root finding algorithms.
|
|
* Implemented the inverses of the incomplete gamma and beta functions.
|
|
* Rewrite erf/erfc as rational approximations (valid to 128-bit precision).
|
|
* Integrated the statistical results generated from
|
|
the test data with Boost.Test: uses a database of expected
|
|
results, indexed by test, floating point type, platform, and compiler.
|
|
* Improved lgamma near 1 and 2 (rational approximations).
|
|
* Improved erf/erfc inverses (rational approximations).
