When converting Matlab code it might be necessary to first reshape a matrix to a linear sequence, perform some indexing operations and then reshape back. As reshape (usually) produces views onto the same storage, it should be possible to do this fairly efficiently. Note that the scan order ...

Due to a regression in OpenBLAS on windows, the performance improvements when using multiple threads for OpenBLAS 0.3.26 were reverted. (gh-27147) ma.covandma.corrcoefare now significantly faster The private function has been refactored along withma.covand ...
Here’s the difference: NumPy arrays use commas between axes, so you can index multiple axes in one set of square brackets. An example is the easiest way to show this off. It’s time to confirm Dürer’s magic square! The number square below has some amazing properties. If you add up...
