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

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

       INTEGER N, INCX, INCY
       DOUBLE PRECISION ALPHA
       DOUBLE PRECISION X(*), Y(*)

       SUBROUTINE DAXPY_64(N, ALPHA, X, INCX, Y, INCY)

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

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

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

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

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

   C INTERFACE
       #include <sunperf.h>

       void  daxpy(int	n,  double  alpha, double *x, int incx, double *y, int
		 incy);

       void daxpy_64(long n, double alpha, double *x, long  incx,  double  *y,
		 long incy);

PURPOSE
       daxpy  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)
		 ( 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)
		 (  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.
