How do you round UP a number in Python?

Your requirement to have different numbers of changes per row, also isn't covered here. Again you could sample more matrices than yo...
How do I assign an alias to a function name in C++?
...te<typename T>
constexpr auto alias_to_old = old_function<T>;
Moreover, starting with C++11 you have a function called std::mem_fn that allows to alias member functions. See the following example:
