Aha. 'Arbitrary function' <> 'arbitrary function that is vectorized to operate on scalar elements of an array'.

I also wrote about sine standing in for an arbitrary function. (And - we are back to first question :)).

Replace 'sin(x)' with 'abracadabra(x)' - now what do I do?

I wished to check that this snippet - nay, pattern - could not be re-engineered using "arrayfun" or in another way.

It doesn't look like it can, but many thanks to John for taking a look.
