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 > > > > _______________________________________________ > NumPy-Discussion mailing list > NumPy-Discussion@scipy.org > http://mail.scipy.org/mailman/listinfo/numpy-discussion > _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
