ZLARND returns a random complex number from a uniform or normal


 distribution.

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.

  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.
