In fact, John, please do! As your own "loop assignment" shows, the problem you're experiencing is not inherent to Matrix_cyclo_dense, it's just overhead in creating all these intermediate lists. It's straightforward to refactor that bit of code and you have a motivation for it now. Representing a dense matrix as sparse will break you up later, even if initial construction doesn't run into the same pitfall. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
