\begin{usage}
maxInvertibleSubmatrix~a\\ maxInvertibleSubmatrix!~a
\end{usage}


Signature


\begin{params}
{\em a} & M & A matrix\\
\end{params}

\begin{retval}
Returns $([r_1,\dots,r_r], [c_1,\dots,c_r])$where $r$\ is the ra...
...ed by the intersections of the rows $r_i$and $c_i$\ is invertible.
\end{retval}

\begin{remarks}
maxInvertibleSubmatrix!~does not make a copy of $a$, but performs all the
computations in--place, modifying the entries of $a$.
