Identify basis functions indices that are non-zero at each point.

Parameters

• points (np.ndarray) – list of points.

• knot_sequence (np.ndarray) – list of knot positions.

Returns

array of points repeated four times idx (np.ndarray): corresponding basis function index for each

point (four each).

Return type

points (np.ndarray)
