           SLARUV returns a vector of n random real numbers from a uniform distribution.

Function/Subroutine Documentation

   subroutine slaruv (integer, dimension( 4 )ISEED, integerN, real, dimension( n )X)
       SLARUV returns a vector of n random real numbers from a uniform distribution.

       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.
