$\begin{usage} extendedRowEchelon!(a, r, c, p) \end{usage}$

Signature

extendedRowEchelon!: (A A Z,Z,Z) $\to$ (A Z, Z, A Z, Z, A A Z)

where
Z == MachineInteger

A == PrimitiveArray

$\begin{params} {\em a} & \htmlref{\texttt{PrimitiveArray}}{PrimitiveArray} \ht... ... & \htmlref{\texttt{MachineInteger}}{MachineInteger} & A prime\\\end{params}$

$\begin{descr} We say that a matrix $a$\ is in REF if there are $r$\ (the rank)... ...ormation matrix {\em u} is stored as entry $(p(i),j)$\ in {\em w}.\end{descr}$

$\begin{remarks} Does not make a copy of $a$, but performs all the computations in--place, modifying the entries of $a$. \end{remarks}$
