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.

    !>
    !>  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.
