SSWAP

Function/Subroutine Documentation

  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:
    N

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

    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
