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.
           !>
