Predominantly this is a TODO list, or a list of possible future enhancements.
|
|
Items labled "High Priority" effect the proper functioning of the
|
|
component, and should be fixed as soon as possible. Items labled "Medium
|
|
Priority" are desirable enhancements, often pertaining to the performance
|
|
of the component, but do not effect it's accuracy or functionality. Items labled
|
|
"Low Priority" should probably be investigated at some point. Such
|
|
classifications are obviously highly subjective.
|
|
</p>
|
|
<p>
|
|
If you don't see a component listed here, then we don't have any known issues
|
|
with it.

Potentially, there could be native support for <code class="computeroutput"><span class="identifier">cyl_bessel_j_prime</span><span class="special">()</span></code> and <code class="computeroutput"><span class="identifier">cyl_neumann_prime</span><span class="special">()</span></code>. One could also imagine supporting the zeros
|
|
thereof, but they might be slower to calculate since root bracketing might
|
|
be needed instead of Newton iteration (for the lack of 2nd derivatives).
|
|
</p>
|
|
<p>
|
|
Since Boost.Math's Bessel functions are so excellent, the quick way to <code class="computeroutput"><span class="identifier">cyl_bessel_j_prime</span><span class="special">()</span></code>
|
|
and <code class="computeroutput"><span class="identifier">cyl_neumann_prime</span><span class="special">()</span></code>
|
|
would be via relationship with <code class="computeroutput"><span class="identifier">cyl_bessel_j</span><span class="special">()</span></code> and <code class="computeroutput"><span class="identifier">cyl_neumann</span><span class="special">()</span></code>.

There is a problem area at arbitrary precision when <span class="emphasis"><em>a</em></span>
|
|
is very close to 1. However, note that the value for <span class="emphasis"><em>T(h, 1)</em></span>
|
|
is well known and easy to compute, and if we replaced the <span class="emphasis"><em>a<sup>k</sup></em></span>
|
|
terms in series T1, T2 or T4 by <span class="emphasis"><em>(a<sup>k</sup> - 1)</em></span> then we would
|
|
have the difference between <span class="emphasis"><em>T(h, a)</em></span> and <span class="emphasis"><em>T(h,
|
|
1)</em></span>. Unfortunately this doesn't improve the convergence of those
|
|
series in that area. It certainly looks as though a new series in terms of
|
|
<span class="emphasis"><em>(1-a)<sup>k</sup></em></span> is both possible and desirable in this area, but
|
|
it remains elusive at present.
