Yes, simp:false turns off all simplifications. But you should keep in mind
that much of what Maxima does is via simplification, including matrix
multiplication. In particular, you might be expecting
matrix([a,b]).matrix([b],[-2*a]) to give you a*b + b*(-2*a) instead of
-a*b. But in fact it will simply remain as
matrix([a,b]).matrix([b],[-2*a]).
