ZLARNV(l)					)					ZLARNV(l)

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

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

	   INTEGER	  IDIST, N

	   INTEGER	  ISEED( 4 )

	   COMPLEX*16	  X( * )

PURPOSE
       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.
