I don't know much about the signal processing toolbox.
There are some ways that you might transfer stuff that
is actually polynomial, back to maxima. e.g. prony uses
polynomials encoded as an array!
But I don't know where there may be important leverage from
symbols, if anywhere.
Starting with duplicating the numeric is what I was
initially suggesting.
