i need use beta distribution , inverse beta distribution in project.

there quite complicated implementation in gsl, don't want use such big library 1 function.

i either, implement on own or link simple library. know sources me? i'm looking books/articles numerical approximation of beta cdf and inverse, libraries implemented. other suggestions appreciated.
programming language, c++/c# preffered.

here managed c++ library has beta cdf , inverse: dcdflib. it's port of popular fortran/c library of same name. if have questions how use code, i'm familiar , can help.

you take dcdflib , delete don't use, it's still going big. implementing beta cdf , inverse accurately wide range of parameters complicated.
