Boost Basic Linear Algebra - Release Notes

Release 1.52.0

improvements

• [4024] improve performance of inplace_solve
• [6511] Division by scalar should use enable_if<>
• [7297] Make the free functions 'num_columns' and 'num_rows' support the uBLAS traits system and better work with expression types

bug fixes

• [7296] fixes and improvements to test utility functions
• [7363] fixed coordinate_matrix::sort() for gcc 4.7 and others

Release 1.43.0

bug fixes

• [3968] fixed coordinate_matrix sort problem on MSVC10
• [3539] changed computation of norm_inf for complex types to match mathematical definition.
  Note: This might cause a performance drop because now std::abs(z) is called for each vector element. The old implementation used std::max(std::abs(real(z)),std::abs(imag(z)). Further norm_inf and norm_1 will now return the same values for complex vector.
• [3501] Moved free functions in concepts.hpp into anonymous namespace.

Release 1.41.1

new features

• Move semantics of vector/matrix container assignments have been implemented. They can be enabled by setting BOOST_UBLAS_MOVE_SEMANTICS. More details are on the preprocessor options page.
• Introduce new free functions. See [3449], the new tests in libs/numeric/ublas/test and the inline documentation of the files in boost/numeric/ublas/operation/.

bug fixes

• [3293] Fix resizing problem in identity_matrix
• [3499] Add DefaultConstructible to concept checks

Release 1.40.0 and before

• Release notes were not available in this form.
