Follow-up Comment #15, bug #46103 (project octave): A sidenote on the questions of sparsity: blkdiag() returns sparse if one of the arguments is sparse. I believe diagonal matrices - at least here - should be considered sparse rather that full? Is there a general rule on which side diagonal matrix falls? I wonder if issparse() should return true for diagonal matrix? _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?46103> _______________________________________________ Meddelandet skickades via/av Savannah http://savannah.gnu.org/
