RedHat 9 (Linux i386) - man page for dlarnv (redhat section l)

DLARNV(l)					)					DLARNV(l)

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.
