Now my second question (extending the second one). Assume that I have a 'List',
like the one before:
\begin{axiom}
[[- 1,3,- 3,1],[3,- 6,3],[- 3,3],[1]]
\end{axiom}
(which is calculated from some earlier expressions). How can I convert it into
a 'SquareMatrix'. Namely I want to have a matrix like:
\begin{axiom}
A := matrix[[- 1,3,- 3,1],[3,- 6,3,0],[- 3,3,0,0],[1,0,0,0]]
\end{axiom}
so that I can do
\begin{axiom}
vp := vector[p0,p1,p2,p3]
\end{axiom}
and
\begin{axiom}
vp * A
\end{axiom}
