NAME
       TESTING/MATGEN/dlarnd.f

SYNOPSIS
   Functions/Subroutines
       double precision function dlarnd (idist, iseed)
           DLARND

Function/Subroutine Documentation
   double precision function dlarnd (integer idist, integer, dimension( 4 )
       iseed)
       DLARND

       Purpose:


            DLARND returns a random real number from a uniform or normal
            distribution.

       Parameters
           IDIST

                     IDIST is INTEGER
                     Specifies the distribution of the random numbers:
                     = 1:  uniform (0,1)
                     = 2:  uniform (-1,1)
                     = 3:  normal (0,1)

           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.

       Further Details:


             This routine calls the auxiliary routine DLARAN to generate a random
             real number from a uniform (0,1) distribution. The Box-Muller method
             is used to transform numbers from a uniform to a normal distribution.
