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 BoxMuller method is used to transform numbers from a uniform to a normal distribution.
