Hi all. Sorry if this question has already been asked. I've searched the archive, but could not find anything related, so here is my question. I'm using np.histogram on a 4000x4000 array, each with 200 bins. I do that on both dimensions, meaning I compute 8000 histograms. It takes around 5 seconds (which is of course quite fast). I was wondering why np.histogram does not accept an axis parameter so that it could work directly on the array without me having to write a loop. Or maybe did I miss some parameters using np.histogram. Thanks. Éric. Un clavier azerty en vaut deux ---------------------------------------------------------- Éric Depagne [email protected]
