When to use xarray over numpy for medium rank multidimensional data?

I have some multidimensional data and was wondering if i should use xarray when speed is one, albeit not highest, of my concerns. I have a 4D array so it’s not so big as to preclude me from using numpy. The coordinates/indices are vital for one dimension but not so for all the others. I’ll have to do slight book-keeping

Discrete Laplacian (del2 equivalent) in Python

numpy python scientific-computing scipy

I need the Python / Numpy equivalent of Matlab (Octave) discrete Laplacian operator (function) del2(). I tried couple Python solutions, none of which seem to match the output of del2. On Octave I have this gives the result On Python I tried which gives the result I also tried That gives the result So none of the outputs seem to
