Module rgsl::gamma_beta

This following routines compute the gamma and beta functions in their full and incomplete forms, as well as various kinds of factorials.

Modules

beta
factorials	Although factorials can be computed from the Gamma function, using the relation n! = \Gamma(n+1) for non-negative integer n, it is usually more efficient to call the functions in this section, particularly for small values of n, whose factorial values are maintained in hardcoded tables.
gamma	The Gamma function is defined by the following integral,
