Definition
::::::::::


Input ports
...........

    **A**  table
        A

    **V**  table
        V


Output ports
............

    **result**  table
        result




Configuration
.............

    **Combinations** (combinations)
        Determines which combinations of signals are operated on.
    **Mode** (mode)
        Mode for handling border data.

        "Full" applies operation on each point of overlap, giving a larger output than inputs and boundary effects may be seen.

        "Same" limits output length to max of input lengths and boundary effects are still visible.

        "Valid" performs operation only on fully overlapping data
    **Operation** (operation)
        Operation to perform
