This is exactly what I'm looking for at this point. To answer Ray's
question in a round-about indirect way, the first use case I have is
for ODE and integral simplification, i.e. I'd like to be able to send
a CL form specifying one or the other, and get a simplified form back.
I'm assuming that I might need to appropriately translate or embed,
but in a sense, I'd like to be able to do something like write a
MaximaWrapper package which I could then do:
(setf OldFunction '(form denoting in lisp notation (some expression)
to (simplify) which would be ODE, integral, or mixed))
(setf newFunction (Tony'sMaximaWrapper::simplify OldFunction)
for later eval'ing of the newFunction in the right
closure/environment. Basically, stripping away the current Maxima
notation into something more directly CL-like.
Robert hit it on the head elsewhere in this thread -- one statistical
application I'm quite keen on is Bayesian nonlinear heirarchical
regression analysis where the mean form is ODE specified. (kinetics
equations in systems biology and pharmacokinetics).

Built on CFFI.
(there's another one out there built directly using SBCL's FFI as well).
