[Numpy-discussion] Re: Switching default order to column-major

2023-11-13 Thread Sebastian Berg
Few things in the Python API care about order, but there are also quite a few places that will return C-order (and are faster for C-order inputs) whether you change those defaults or not. The main issue is that e.g. some cython wrappers will probably assume that the newly created array is C-order.
