05 Aug 2009 Don't let that INV go past your eyes; to solve that system, FACTORIZE! A simple-to-use object-oriented method for solving linear systems and least-squares problems. Author: Tim Davis

All in all this package is a great idea and it looks like a first class implementation. As such, I'd like to help improve it by pointing out an issue. I am trying to solve Ax=-b, so I type in x=-inverse(A)*b, but I get the following error:

??? Undefined function or method 'uminus' for input arguments of type 'factorization_dense_lu'.

The work around is simple: x=inverse(A)*(-b). However, these are mathematically equivalent, so both should work.
