are you aware of a trusted (i.e. efficient and accurate) implementation of special math functions (like gamma, beta, error and inverse error functions) for the C language available with a non-gpl license? BSD or MIT licenses are fine.
So something like:
http://www.gnu.org/software/gsl/manual/html_node/Special-Functions.html
but with a more permissive license. I am aware boost have something similar but it’s a bit overkill to add dependency on boost just for this…
Moreover C would be preferable in this context…
Thanks!
