splinepy.spline.Spline.basis_derivative_and_support

Spline.basis_derivative_and_support(queries, orders, nthreads=None)

Returns derivative of basis functions and their support ids of given queries. Same as calling basis_derivative and support at the same time.

Parameters:

• queries ((n, para_dim) array-like)

• orders ((para_dim,) or (m, para_dim) array-like)

• nthreads (int)

Returns:

• basis_derivatives ((n, m, prod(degrees + 1)) np.ndarray) – Iff m == 1, it will have (n, prod(degrees + 1)) shape.

• supports ((n, prod(degrees + 1)) np.ndarray)
