DLARUV(l)					)					DLARUV(l)

NAME
       DLARUV - return a vector of n random real numbers from a uniform (0,1)

SYNOPSIS
       SUBROUTINE DLARUV( ISEED, N, X )

	   INTEGER	  N

	   INTEGER	  ISEED( 4 )

	   DOUBLE	  PRECISION X( N )

PURPOSE
       DLARUV  returns	a vector of n random real numbers from a uniform (0,1) distribution (n <=
       128).

       This is an auxiliary routine called by DLARNV and ZLARNV.

ARGUMENTS
       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. N <= 128.

       X       (output) DOUBLE PRECISION array, dimension (N)
	       The generated random numbers.

FURTHER DETAILS
       This  routine  uses a multiplicative congruential method with modulus 2**48 and multiplier
       33952834046453 (see G.S.Fishman,
       2**b: an exhaustive analysis for b = 32 and a partial analysis for b =  48',  Math.  Comp.
       189, pp 331-344, 1990).

       48-bit integers are stored in 4 integer array elements with 12 bits per element. Hence the
       routine is portable across machines with integers of 32 bits or more.
