Usage
Calculates the reduced row echelon form of a matrix using Gauss
Jordan elimination with partial pivoting. The generic syntax
for rref is
R = rref(A)
A default tolerance of max(size(A))*eps*norm(A,inf) is used to
detect negligible column elements. The second form of rref
returns a vector k as well as R
[R,k] = rref(A)
where k is a vector that correponds to the columns of A
used as pivot columns. If you want to control the tolerance
used to identify negligible elements, you can use the form
[R,k] = rref(A, tolerance)
This implementation of rref is based on the one from
the matcompat lib for octave. It is copyright Paul Kienzle,
