korc_rnd_numbers Module

  1. korc_rnd_numbers.f90
  2. korc_rnd_numbers

This subroutines were taken from Numerical Recipes in Fortran 90, and provide a way for generating random numbers of 'better quality' in a faster way than build-in Fortran random generators (at least
better than those of Fortran 77). For more details we refer the user to Numerical Recipes in Fortran 90.
