[Numpy-discussion] Special matrices with structure?

2012-02-23 Thread Jaakko Luttinen
Hi! I was wondering whether it would be easy/possible/reasonable to have classes for arrays that have special structure in order to use less memory and speed up some computations? For instance: - symmetric matrix could be stored in almost half the memory required by a non-symmetric matrix - diago
