NAME

       LAPACK-3 - returns a vector of n random real numbers from a uniform or normal distribution

SYNOPSIS

       SUBROUTINE SLARNV( IDIST, ISEED, N, X )

           INTEGER        IDIST, N

           INTEGER        ISEED( 4 )

           REAL           X( * )

PURPOSE

       SLARNV 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) REAL array, dimension (N)
                The generated random numbers.

FURTHER DETAILS

        This routine calls the auxiliary routine SLARUV 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.
