   C INTERFACE
       #include <sunperf.h>

       void cvmul(int n, complex *alpha, complex *x, int incx, complex *y, int
                 incy, complex *beta, complex *z, int incz);

PURPOSE
       cvmul computes the scaled product of complex vectors:
         z(i) = ALPHA * x(i) * y(i) + BETA * z(i)
       for 1 <= i <= N.


ARGUMENTS
       N (input)
                 Length  of  the vectors.  N >= 0.  Returns immediately if N =
                 0.


       ALPHA (input)
                 Scale factor on the multiplicand vectors.


       X (input)
                  dimension(*)
                 Multiplicand vector.


       INCX (input)
                 Stride between elements of the multiplicand vector X.


       Y (input)
                  dimension(*)
                 Multiplicand vector.


       INCY (input)
                 Stride between elements of the multiplicand vector Y.


       BETA (input)
                 Scale factor on the product vector.


       Z (input/output)
                  dimension(*)
                 Product vector.  On exit, z(i) = ALPHA * x(i) * y(i) + BETA *
                 z(i).


       INCZ (input)
                 Stride between elements of Z.
