NAME
     caxpy - Compute y := alpha * x + y

SYNOPSIS
     SUBROUTINE CAXPY (N, ALPHA, X, INCY, Y, INCY )

     COMPLEX ALPHA

     INTEGER INCX, INCY, N

     COMPLEX X( * ), Y( * )



     #include <sunperf.h>

     void caxpy (int n, complex *za, complex *zx, int incx,  com-
               plex *zy, int incy);

PURPOSE
     CAXPY - Compute y := alpha * x + y where alpha is  a  scalar
     and x and y are n-vectors.


PARAMETERS
     N         - INTEGER.
               On entry, N specifies the number  of  elements  in
               the  vector.   N must be at least one for the sub-
               routine to have any visible effect.  Unchanged  on
               exit.

     ALPHA     - COMPLEX.
               On  entry,  ALPHA  specifies  the  scalar   alpha.
               Unchanged on exit.

     X         - COMPLEX
               array of DIMENSION at least ( 1 + ( n -  1  )*abs(
               INCX  )  ).  Before entry, the incremented array X
               must contain the vector x.  Unchanged on exit.

     INCX      - INTEGER.
               On entry, INCX specifies  the  increment  for  the
               elements  of  X. INCX must not be zero.  Unchanged
               on exit.

     Y         - COMPLEX
               array of DIMENSION at least ( 1 + ( m -  1  )*abs(
               INCY  ) ).  On entry, the incremented array Y must
               contain the vector y. On exit, Y is overwritten by
               the updated vector y.

     INCY      - INTEGER.
               On entry, INCY specifies  the  increment  for  the
               elements  of  Y. INCY must not be zero.  Unchanged
               on exit.
