SLARND

Function/Subroutine Documentation

real function SLARND (integer idist, integer, dimension( 4 ) iseed)

SLARND

Purpose:

!>
!> SLARND 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
