    • beta

      public static double beta(double a, double b)
      Value of the beta function evaluated with arguments a and b. This routine is a translation into C of a Fortran subroutine by W. Fullerton of Los Alamos Scientific Laboratory. Some modifications have been made so that the routines conform to the IEEE 754 standard.
