numpy.ma.flatnotmasked_edges(a)

nditer.remove_axis(i) Removes axis i from the iterator. Requires that the flag ?multi_index? be enabled

numpy.c_ = Translates slice objects to concatenation along the second axis. This is short-hand for np.r_['-1,2,0', index

masked_array.mask Mask

numpy.ma.set_fill_value(a, fill_value)

numpy.matlib.eye(n, M=None, k=0, dtype=)

numpy.ma.mask_cols(a, axis=None)

chararray.upper()
