Well, that seems like a good idea, but I think I'll plow ahead with
pattern matching. Maybe someone will implement an approach via residues.
It will be interesting to compare notes.


I've done both recently (manually, using maxima for algebra and
substitutions since ilt fails). The complex residue method is generally
something I do after pattern matching has failed. So it might make sense to
have it somewhere on the decision tree. I have some older textbooks that
have some quite extensive LaPlace tables that I have yet to find good
replicants of online, and they usually do the trick.

 I really have no idea how Maxima works under the hood. But if it would be
useful to provide some example problem solutions that can be done by hand
but not ilt, I'd be happy to provide a few. Maybe if for no other reason
than to provide some test cases for ilt to eventually work on? Or would a
more extensive Laplace table set be preferable? (For some reason I can't
fond the emailed lust Dimiter sent?)
