symmetrize

mdtools.numpy_helper_functions.symmetrize(a, lower=True, debug=False)[source]

Create a symmetrized copy of a 2-dimensional array.

Parameters:

a (array_like) – 2-dimensional array to symmetrize.
lower (bool, optional) – If True, mirror the lower triangle of a to the upper one. If False, mirror the upper triangle to the lower one. The diagonal of a is unchanged.
debug (bool, optional) – If True, check the input arguments.

Returns:

a_sym (numpy.ndarray) – A symmetrized copy of a.
