SAXPY

Function/Subroutine Documentation

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 ) )
