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

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

       COMPLEX ALPHA
       COMPLEX X(*), Y(*)
       INTEGER N, INCX, INCY

       SUBROUTINE CAXPY_64(N, ALPHA, X, INCX, Y, INCY)

       COMPLEX ALPHA
       COMPLEX X(*), Y(*)
       INTEGER*8 N, INCX, INCY

   F95 INTERFACE
       SUBROUTINE AXPY([N], ALPHA, X, [INCX], Y, [INCY])

       COMPLEX :: ALPHA
       COMPLEX, DIMENSION(:) :: X, Y
       INTEGER :: N, INCX, INCY

       SUBROUTINE AXPY_64([N], ALPHA, X, [INCX], Y, [INCY])

       COMPLEX :: ALPHA
       COMPLEX, DIMENSION(:) :: X, Y
       INTEGER(8) :: N, INCX, INCY

   C INTERFACE
       #include <sunperf.h>

       void caxpy(int n, complex *alpha, complex *x, int incx, complex *y, int
		 incy);

       void caxpy_64(long n, complex *alpha, complex *x,  long	incx,  complex
		 *y, long incy);

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

ARGUMENTS
       N (input)
		 On entry, N specifies the number of elements in  the  vector.
		 N must be at least one for the subroutine to have any visible
		 effect.  Unchanged on exit.

       ALPHA (input)
		 On entry, ALPHA specifies the	scalar	alpha.	 Unchanged  on
		 exit.

       X (input)
		 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 (input)
		 On entry, INCX specifies the increment for the elements of X.
		 Unchanged on exit.

       Y (input/output)
		 array of DIMENSION at least ( 1 + ( n - 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 (input)
		 On entry, INCY specifies the increment for the elements of Y.
		 Unchanged on exit.
