Follow-up Comment #1:

Yes, this is true.  It might be a good addition, but there is also a bigger
strategic issue that is worth thinking about.  The current architecture is
that the movXXX functions are simple in that they do just a little bit of
input validation and then pass on the function to movfun().  This structure
makes maintenance easy and any improvements to movfun() are automatically
reflected in the derivative movXXX functions.  movmean() is a special case in
that there is a convenient kernel that can be used with conv() (which is
written in C++) to accelerate that function.  But other functions, such as
movmad(), do not seem to have any easy mapping on to conv().  Perhaps it would
be better to re-write movfun() in C++ where loops would not be a problem.
