complex function clarnd (idist, iseed)
CLARND

CLARND

Purpose:

 CLARND 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 SLARAN 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.
