D.3.2.11 gaussred

Procedure from library linalg.lib (see linalg_lib).

Usage:
gaussred(A); A any constant matrix

Return:
list Z: Z[1]=P , Z[2]=U , Z[3]=S , Z[4]=rank(A)
gives a row reduced matrix S, a permutation matrix P and a normalized lower triangular matrix U, with P*A=U*S

Note:
This procedure is designed for teaching purposes mainly. The straight forward implementation in the interpreted library is not very efficient (no standard basis computation).

Example:
