I'm convinced that I saw a while ago a function that uses a list of interval boundaries to index into an array, either to iterate or to take. I thought that's very useful, but didn't make a note.
Now, I have no idea where I saw this (I thought numpy), and I cannot find it anywhere.
any clues?
Some possibilities:
np.array_split() np.split()
perfect (haven't gotten further down the list yet)
np.split(np.arange(15), [3,4,6, 13]) [array([0, 1, 2]), array([3]), array([4, 5]), array([ 6, 7, 8, 9, 10, 11, 12]), array([13, 14])]
docstring says equal size, which fortunately is not correct http://docs.scipy.org/doc/numpy/reference/generated/numpy.split.html Thank you, Josef
np.ndindex() np.nditer() np.nested_iters() np.ravel_multi_index()
Your description reminded me of a function I came across once, but I can't remember if one of these was it or if it was another one.
IHTH, Ben Root
