sswap()

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

SSWAP

Purpose:

    SSWAP interchanges two vectors.
    uses unrolled loops for increments equal to 1.

Parameters

[in]	N	N is INTEGER number of elements in input vector(s)
[in,out]	SX	SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
[in]	INCX	INCX is INTEGER storage spacing between elements of SX
[in,out]	SY	SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) )
[in]	INCY	INCY is INTEGER storage spacing between elements of SY
