Hi, I have a 2D numpy array like this:
[[1,2,3,4], [1,2,3,4], [1,2,3,4] [1,2,3,4]] Is there any fast way to convert this array to [[1,1,1,1], [2,2,2,2] [3,3,3,3] [4,4,4,4]] In general I would need to retrieve every nth element of the interior arrays in to single arrays. I know I can loop over and do this, but I have really big arrays and I need the fastest way to do this. Thanks for your help, -- https://mail.python.org/mailman/listinfo/python-list
