DLARUV(3)      LAPACK routine of NEC Numeric Library Collection      DLARUV(3)



NAME
       DLARUV

SYNOPSIS
       SUBROUTINE DLARUV (ISEED, N, X)



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)
                     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         (input)
                     N is INTEGER
                     The number of random numbers to be generated. N <= 128.

           X         (output)
                     X is 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.

             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.
