Just FYI, "2*x.*y" is the current output from Symbolic for 
"function_handle(2*x*y)".

This is a doctest right?  You can protect your test from old versions like:

## @example
## @c doctest: +SKIP_IF(compare_versions (sympref('version'), '2.5.0', '<'))
## ...
## @end example

(Note this needs latest doctest-0.5.0)

Background: old versions of Symbolic/SymPy used the Octave command 
"vectorize" (which gives "2.*x.*y") but these days SymPy does the Octave 
code generation for us.
