SYNOPSIS

  Functions/Subroutines
complex *16 function zlarnd (idist, iseed)
ZLARND

Function/Subroutine Documentation

  complex*16 function zlarnd (integer idist, integer, dimension( 4 ) iseed)

ZLARND

Purpose:

     ZLARND returns a random complex number from a uniform or normal
     distribution.

Parameters
    IDIST

              IDIST is INTEGER
              Specifies the distribution of the random numbers:
              = 1:  real and imaginary parts each uniform (0,1)
              = 2:  real and imaginary parts each uniform (-1,1)
              = 3:  real and imaginary parts each normal (0,1)
              = 4:  uniformly distributed on the disc abs(z) <= 1
              = 5:  uniformly distributed on the circle abs(z) = 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.
