@hamza-712 Actually, you can already calculate the correlation of two arrays by flipping one of them, and calling convolve. Would that not work for you? If you use slices as in a[::-1], then you don't even waste RAM, because the slice is just a view, so no memory allocation takes place.

@v923z Thanks, I've implemented just like you said.
