NAME
       SRC/zlarnv.f

SYNOPSIS
   Functions/Subroutines
       subroutine zlarnv (idist, iseed, n, x)
           ZLARNV returns a vector of random numbers from a uniform or normal
           distribution.

Function/Subroutine Documentation
   subroutine zlarnv (integer idist, integer, dimension( 4 ) iseed, integer n,
       complex*16, dimension( * ) x)
       ZLARNV returns a vector of random numbers from a uniform or normal
       distribution.

       Purpose:


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

       Parameters
           IDIST

                     IDIST is 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

                     ISEED is 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

                     N is INTEGER
                     The number of random numbers to be generated.

           X

                     X is 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.
