SYNOPSIS
Functions/Subroutines
subroutine slaruv (ISEED, N, X)
SLARUV
Function/Subroutine Documentation
subroutine slaruv (integer, dimension( 4 )ISEED, integerN, real, dimension( n )X)
SLARUV
Purpose:
SLARUV returns a vector of n random real numbers from a uniform (0,1)
distribution (n <= 128).
This is an auxiliary routine called by SLARNV and CLARNV.
Parameters:
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. N <= 128.
X
X is REAL 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,
'Multiplicative congruential random number generators with modulus
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.
