unique#

Quaternion.unique(return_index: bool = False, return_inverse: bool = False) → Tuple[Object3d, ndarray, ndarray] | Tuple[Object3d, ndarray] | Object3d[source]#

Return a new object containing only this object’s unique entries.

Unless overridden, this method returns the numerically unique entries. It also removes zero-entries which are assumed to be degenerate.

Parameters:

return_index: If True, will also return the indices of the (flattened) data where the unique entries were found.
return_inverse: If True, will also return the indices to reconstruct the (flattened) data from the unique data.

Returns:

dat: The numerically unique entries.
idx: The indices of the unique data in the (flattened) array if return_index=True.
inv: The indices of the (flattened) data in the unique array if return_inverse=True.
