NAME
       clarnv.f -

SYNOPSIS
   Functions/Subroutines
       subroutine clarnv (IDIST, ISEED, N, X)
           CLARNV returns a vector of random numbers from a uniform or normal
           distribution.

Function/Subroutine Documentation
   subroutine clarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN,
       complex, dimension( * )X)
       CLARNV returns a vector of random numbers from a uniform or normal
       distribution.

       Purpose:

            CLARNV 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 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.
