t of the sparse factorizations used in MATLAB!
%
% INV: slow and inaccurate.  Wins big on ease-of-use, though, since it's a
%       direct plug-in for all your nice mathematical formulas.
%
% No method is best on all three criterion: speed, accuracy, and ease of
% use.
%
% Is there a solution?  Yes ... keeping reading ...

%% The FACTORIZE object to the rescue
%
% The FACTORIZE method is just as easy to use as INV, but just as fast and
% accurate as BACKSLASH, LU, QR, CHOL, and LINSOLVE.
