```CLARNV(1)	    LAPACK auxiliary routine (version 3.2)	     CLARNV(1)

NAME
CLARNV - returns a vector of n random complex numbers from a uniform or
normal distribution

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

INTEGER	  IDIST, N

INTEGER	  ISEED( 4 )

COMPLEX	  X( * )

PURPOSE
CLARNV 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 array, dimension (N)
The generated random numbers.

FURTHER DETAILS
This routine calls the auxiliary routine SLARUV 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.
