Utilities

ela.utils module

ela.utils.flip(m, axis)

Reverse the order of elements in an array along the given axis. Only use if numpy < 1.12, otherwise use np.flip

The shape of the array is preserved, but the elements are reordered. If using numpy < 1.12, np.flip is not available (stemmed from Anaconda for windows). # see https://stackoverflow.com/a/45707308/2752565

Parameters

• m (array_like) – Input array.

• axis (None or int, optional) – Axis or axes along which to flip over. The default, axis=None, will flip over all of the axes of the input array. If axis is negative it counts from the last to the first axis. If axis is a tuple of ints, flipping is performed on all of the axes specified in the tuple.

Returns

flipped array. A view of m with the entries of axis reversed. Since a view is returned, this operation is done in constant time.

Return type

array_like
