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).
