NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     SUBROUTINE	ZLARNV(	IDIST, ISEED, N, X )

	 INTEGER	IDIST, N

	 INTEGER	ISEED( 4 )

	 COMPLEX*16	X( * )

PURPOSE    [Toc]    [Back]

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

ARGUMENTS    [Toc]    [Back]

     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.
