kernel!

$\begin{usage} kernel!(m, f) \end{usage}$

Signature

kernel!: (M, M $\to$ M) $\to$ M

$\begin{params} {\em m} & M & A matrix\\ {\em f} & M $\to$\ M & Computes a kernel\\\end{params}$

$\begin{retval} Returns a basis for the kernel of m, uses a specialized algorith... ...verdetermined, uses f when the system is no longer overdetermined. \end{retval}$

$\begin{remarks} Can destroy m. \end{remarks}$
