Return type:

NDArray

Example

>>> import autograd.numpy as np
>>> from tidy3d.plugins.autograd.invdes.symmetries import symmetrize_rotation
>>> arr = np.asarray([
...     [0, 0, 0],
...     [1, 5, 2],
...     [8, 1, 8]
... ])
>>> res = symmetrize_rotation(arr)
>>> assert np.all(np.isclose(res, np.asarray([
...     [4, 1, 4],
...     [1, 5, 1],
...     [4, 1, 4]
... ])))
