I apologise if I'm asking an obvious question or one that has already been addressed. I've tried to understand the documentation in the numpy manual on slicing, but I'm a bit lost. I'm trying to do indexing using both slices and index lists. I have a problem when I do something like: x[0, :,

[Numpy-discussion] Optical autocorrelation calculated with numpy is slow

Hi, I wrote a script to calculate the *optical* autocorrelation of an electric field. It's like the autocorrelation, but sums the fields instead of multiplying them. I'm calculating I(tau) = integral( abs(E(t)+E(t-tau))**2,t=-inf..inf) with script appended at the end. It's too slow for my purp

I have a process that stores a number of sets of 3 arrays output which can either be stored as a few .npy files or an .npz file with the same keys in each file (let's say, writing roughly 10,000 npz files, all containing the same keys 'a', 'b', 'c'). If I run multiple processes on the same machine
