A new Fortran code to compute Legendre functions

Computation and inversion of the gamma cumulative distribution (central and non-central)
This package includes the computation and inversion of Marcum functions as well as other
functions which are used in this computation: gamma function, logarithm of the gamma
function, regulated gamma function, error function...
           

Software under development:
