NAME
       TESTING/MATGEN/slaran.f

SYNOPSIS
   Functions/Subroutines
       real function slaran (iseed)
           SLARAN

Function/Subroutine Documentation
   real function slaran (integer, dimension( 4 ) iseed)
       SLARAN

       Purpose:


           !>
           !> SLARAN returns a random real number from a uniform (0,1)
           !> distribution.
           !>

       Parameters
           ISEED

           !>          ISEED is INTEGER array, dimension (4)
           !>          On entry, the seed of the random number generator; the array
           !>          elements must be between 0 and 4095, and ISEED(4) must be
           !>          odd.
           !>          On exit, the seed is updated.
