subroutine saxpy (integer N, real SA, real, dimension(*) SX, integer INCX, real, dimension(*) SY, integer INCY)

SAXPY

Purpose: 

    SAXPY constant times a vector plus a vector.
    uses unrolled loops for increments equal to one.


 

Parameters:

N 

          N is INTEGER
         number of elements in input vector(s)


SA 

          SA is REAL
           On entry, SA specifies the scalar alpha.


SX 

          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )


INCX 

          INCX is INTEGER
         storage spacing between elements of SX


SY 

          SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) )


INCY 

          INCY is INTEGER
         storage spacing between elements of SY
