    NAME
         dlarnv - return a vector of n random  real  numbers  from  a
         uniform or normal distribution
    
    SYNOPSIS
         SUBROUTINE DLARNV( IDIST, ISEED, N, X )
    
         INTEGER IDIST, N
    
         INTEGER ISEED( 4 )
    
         DOUBLE PRECISION X( * )
    
    
    
         #include <sunperf.h>
    
         void dlarnv(int idist, int *iseed, int n, double *x);
    
    PURPOSE
         DLARNV returns a vector of n random real numbers from a uni-
         form 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) DOUBLE PRECISION array, dimension (N)
                   The generated random numbers.
    
    FURTHER DETAILS
         This routine calls the auxiliary routine DLARUV 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 nor-
         mal distribution.
