Hi, I think there are some redundancies in the current sparse matrices--
1. In __init__, I think we don't need the branch/conditional ""if callable(args[2]"" because it defeats the reason of having sparse matrices. That will always produce a matrix that does not have a large number of zeroes 2. In __init__, I think we also don't need the else branch. That should be in the normal matrices only, not sparse. I think we should all discuss the adequacy of the above codes. -Saurabh Jha -- You received this message because you are subscribed to the Google Groups "sympy" group.
