  Functions/Subroutines
subroutine dswap (n, dx, incx, dy, incy)
DSWAP

Function/Subroutine Documentation

  subroutine dswap (integer n, double precision, dimension(*) dx, integer incx, double precision, dimension(*) dy, integer incy)

DSWAP

Purpose:

    !>
    !>    DSWAP interchanges two vectors.
    !>    uses unrolled loops for increments equal to 1.
    !>

Parameters
    N

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

    DX

    !>          DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
    !>

    INCX

    !>          INCX is INTEGER
    !>         storage spacing between elements of DX
    !>

    DY

    !>          DY is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) )
    !>

    INCY

    !>          INCY is INTEGER
    !>         storage spacing between elements of DY
