       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.
