[section Known Issues, and Todo List]
|
|
|
|
[h4 tgamma]
|
|
|
|
* Can the __lanczos be optimized any further? (low priority)
|
|
|
|
[h4 lgamma]
|
|
|
|
* Improve accuracy near 1 and 2 with either Chebyshev or rational
|
|
approximation. (High priority).
|
|
|
|
[h4 erf/erfc]
|
|
|
|
* Rewrite using either Chebyshev or rational
|
|
approximation. (High priority).
|
|
|
|
[h4 Incomplete gamma]
|
|
|
|
* Implement Temme's asymptotic expansion for large a and z,
|
|
this one is mainly an issue of performance rather than accuracy (medium priority).
|
|
* Double check behavior of the upper fraction when a is very small and z -> 1 (Medium Priority).
|
|
* Double check behavior of the upper fraction when a is very small and z -> 0 (Medium Priority).
|
|
* Double check for opportunities to chain series expansions together, passing
|
|
the result of one into the initial value of the next (Medium Priority).
|
|
* Investigate asymptotic expansions for large a small z and large z small a
|
|
(see A&S) (low priority).
|
|
|
|
|
|
[h4 Beta Function]
|
|
|
|
* No known issues?
|
|
|
|
[h4 Incomplete Beta]
|
|
|
|
* Investigate Didonato and Morris' asymptotic expansion for large a and b
|
|
(medium priority).
|
|
* Double check for opportunities to chain series expansions together, passing
|
|
the result of one into the initial value of the next (Medium Priority).
|
|
* Investigate Didonato and Morris' asymptotic expansion for small a and b
|
|
(low priority).
