Help with using CAS math like Maxima?

BTW, your examples work fine here (see attached), modulo my comments regarding maxima notation in my mail.

> I don?t know if you are using this notation intentionally, but the symbol for matrix multiplication in maxima is a ?dot? as in ?full stop?, not ?\cdot? as your picture seems to show. When you use ?\cdot?, maxima does component-wise multiplication.

> Similarly, maxima uses ?^^n?, not ?^n?, for raising a matrix to n'th power. So, your matrix to the power of -1 in lyx is not the matrix inverse for maxima, if your intention was inverting the matrix. With ?^-1", maxima calculates component-wise inverses (reciprocals).
