    NAME
         zvmul - compute the scaled product of complex*16 vectors
    
         SUBROUTINE ZVMUL(N, ALPHA, X, INCX, Y, INCY, BETA, Z, INCZ)
    
         INTEGER N, INCX, INCY, INCZ
    
         COMPLEX*16 ALPHA, BETA, X(*), Y(*), Z(*)
    
    
    
         #include <sunperf.h>
    
         void zvmul(int n, doublecomplex  *alpha,  doublecomplex  *x,
                   int  incx,  doublecomplex *y, int incy, doublecom-
                   plex *beta, doublecomplex *z, int incz) ;
    
    PURPOSE
         ZVMUL computes the scaled product of complex*16 vectors:
           z(i) = ALPHA * x(i) * y(i) + BETA * z(i)
         for 1 <= i <= N.
    
    ARGUMENTS
         N         (input) INTEGER
                   Length of the vectors.  N >= 0.  ZVMUL will return
                   immediately if N = 0.
    
         ALPHA     (input) COMPLEX*16
                   Scale factor on the multiplicand vectors.
    
         X         (input) COMPLEX*16(*)
                   Multiplicand vector.
    
         INCX      (input) INTEGER
                   Stride between elements of the multiplicand vector
                   X.  INCX > 0.
    
         Y         (input) COMPLEX*16(*)
                   Multiplicand vector.
    
         INCY      (input) INTEGER
                   Stride between elements of the multiplicand vector
                   Y.  INCY > 0.
    
         BETA      (input) COMPLEX*16
                   Scale factor on the product vector.
    
         Z         (output) COMPLEX*16(*)
                   Product vector.  On exit, z(i) = ALPHA  *  x(i)  *
                   y(i) + BETA * z(i).
    
         INCZ      (input) INTEGER
                   Stride between elements of Z.  INCZ > 0.
