Follow-up Comment #2, bug #46103 (project octave): The diagonal matrix class is supposed to be a memory saving optimization. All calculations on diagonal matrices should result in exactly the same behavior as when a full matrix is used. My suggestion would be to change the diagonal class to return an Inf array for a singular matrix the same as is done fore a full matrix. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?46103> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
