NAME
       DLARNV - return a vector of n random real numbers from a uniform or normal distribution

SYNOPSIS
       SUBROUTINE DLARNV( IDIST, ISEED, N, X )

	   INTEGER	  IDIST, N

	   INTEGER	  ISEED( 4 )

	   DOUBLE	  PRECISION X( * )

PURPOSE
       DLARNV returns a vector of n random real numbers from a uniform or normal distribution.

ARGUMENTS
       IDIST   (input) INTEGER
	       Specifies the distribution of the random numbers:
	       = 1:  uniform (0,1)
	       = 2:  uniform (-1,1)
	       = 3:  normal (0,1)

       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) DOUBLE PRECISION 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.
