OK, it looks like the instantiation is not going to change. Could someone interested in Matrix take a look at the other changes:
All indices (except absolute indices) behave like indices to python lists. So negative indices are now supported: M[1,-1] gives the last element of row 1 col_insert(-1, c) inserts c before last column col_insert(M.cols, c) will append c (since M.cols is greater than the last column number) col_insert(oo, c) will append c (since oo is greater than the last column number) The dot product is a little more flexible, returning a list if given anything other than a single row or col project and dot docstrings are expanded coverage has been increased arguments to zeros and ones can be given as foo(i, j) and not only foo((i,j)) and foo(i) -- You received this message because you are subscribed to the Google Groups "sympy" group.
