CUDA内核的更广泛的数学函数库？特别不完整的测试版 [英] a more extensive library of math functions for CUDA kernel? particularly incomplete beta

问题描述

我了解cuda数学库，而cuda 4.1工具包版本具有诸如gamma和bessel函数之类的好东西。我需要正规化的不完全beta函数（也就是beta概率分布的累积分布函数）。

I know about the cuda math library, and the cuda 4.1 toolkit version has good stuff like the gamma and bessel functions. I need the regularized incomplete beta function (a.k.a the cumulative distribution function for the beta probability distribution). Is this available in any open source library?

推荐答案

我对统计函数不了解，但看起来像函数一样Cephes库中的incbet（）可能是一个合理的起点。 Cephes库享有很高的声誉，可通过Netlib随时获得资源。参见 http://www.netlib.org/cephes

I don't know enough about statistical functions, but it looks like the function incbet() in the Cephes library may be a reasonable starting point. The Cephes library has an excellent reputation, and sources are readily available via Netlib. See http://www.netlib.org/cephes

在存档cprob.tgz中有一个文件incbet.c，其中包含incbet（）的源。

Inside the archive cprob.tgz there is a file incbet.c which contains the source for incbet().
