PURPOSE
  ZLARNV - return a vector of n random complex numbers from a uniform or
  normal distribution

SYNTAX
  SUBROUTINE ZLARNV( IDIST, ISEED, N, X )

      INTEGER	     IDIST, N

      INTEGER	     ISEED( 4 )

      COMPLEX*16     X( * )

DESCRIPTION
  ZLARNV returns a vector of n random complex numbers from a uniform or
  normal distribution.

ARGUMENTS
  IDIST	  (input) 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	  (input/output) 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.

  N	  (input) INTEGER
	  The number of random numbers to be generated.

  X	  (output) COMPLEX*16 array, dimension (N)
	  The generated random numbers.

FURTHER DETAILS
  This routine calls the auxiliary routine DLARUV to generate random real
  numbers from a uniform (0,1) distribution, in batches of up to 128 using
  vectorisable code. The Box-Muller method is used to transform numbers from
  a uniform to a normal distribution.
