51  // be used in functions like slidingXXX.
52  // Virtual functions instead of templated functions are used to avoid
53  // code bloat when used in functions like partialArrayMath. Because a
54  // reduction operation usually takes much more time than the call, using
55  // virtual functions hardly imposes a performance penalty.
