    NAME
         dlaruv - return a vector of n random  real  numbers  from  a
         uniform (0,1)
    
    SYNOPSIS
         SUBROUTINE DLARUV( ISEED, N, X )
    
         INTEGER N
    
         INTEGER ISEED( 4 )
    
         DOUBLE PRECISION X( N )
    
    
    
         #include <sunperf.h>
    
         void dlaruv(int *iseed, int n, double *x) ;
    
    PURPOSE
         DLARUV returns a vector of n random real numbers from a uni-
         form (0,1) distribution (n <= 128).
    
         This is an auxiliary routine called by DLARNV and ZLARNV.
    
    
    ARGUMENTS
         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. N <=
                   128.
    
         X         (output) 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   (see
         G.S.Fishman,
         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.
