splinepy.bspline.BSpline.basis_derivative#
- BSpline.basis_derivative(queries, orders, nthreads=None)#
Returns derivative of basis functions evaluated on the supports of given queries.
- Parameters:
queries ((n, para_dim) array-like)
orders ((para_dim,) or (m, para_dim) array-like)
nthreads (int)
- Returns:
basis_derivatives – Iff m == 1, it will have (n, prod(degrees + 1)) shape.
- Return type:
(n, m, prod(degrees + 1)) np.ndarray
