Hi All, There is an old ticket, #1499 <https://github.com/numpy/numpy/issues/1499>, that suggest adding a segment_axis function.
def segment_axis(a, length, overlap=0, axis=None, end='cut', endvalue=0): """Generate a new array that chops the given array along the given axis into overlapping frames. Parameters ---------- a : array-like The array to segment length : int The length of each frame overlap : int, optional The number of array elements by which the frames should overlap axis : int, optional The axis to operate on; if None, act on the flattened array end : {'cut', 'wrap', 'end'}, optional What to do with the last frame, if the array is not evenly divisible into pieces. - 'cut' Simply discard the extra values - 'wrap' Copy values from the beginning of the array - 'pad' Pad with a constant value endvalue : object The value to use for end='pad' Examples -------- >>> segment_axis(arange(10), 4, 2) array([[0, 1, 2, 3], [2, 3, 4, 5], [4, 5, 6, 7], [6, 7, 8, 9]]) Is there and interest in having this function available?
