C 或 C 的 gamma 或 log gamma 函数
问题说明
我正在寻找 C 或 C 版本的伽马和对数伽马函数.
I am seeking a C or C version of gamma and log gamma functions.
有没有推荐的代码片段或库?
Are there any code pieces or libraries recommended?
如果可能，我想知道实现的原理.
If possible, I want to know the principle of the implementations.
谢谢！！！
正确答案
如果您不能使用 C 11:GNU GSL 拥有您需要的所有 Gamma 函数:http://www.gnu.org/software/gsl/manual/html_node/Gamma-Functions.html#index-gsl_005fsf_005flngamma-583
If you can't use C 11: The GNU GSL has all Gamma function you would ever need: http://www.gnu.org/software/gsl/manual/html_node/Gamma-Functions.html#index-gsl_005fsf_005flngamma-583
或者你可以看看boost的数学特殊函数:http:///www.boost.org/doc/libs/1_53_0/libs/math/doc/sf_and_dist/html/math_toolkit/special/sf_gamma/lgamma.html
Or you can have a look at boost's math special functions: http://www.boost.org/doc/libs/1_53_0/libs/math/doc/sf_and_dist/html/math_toolkit/special/sf_gamma/lgamma.html
