- chaosmagpy.model_utils.pp_from_bspline(coeffs, knots, order)¶
Return a piecewise polynomial from a BSpline representation.
- coeffsndarray, shape (M, D)
Bspline coefficients for the M B-splines parameterizing D dimensions.
- knotsndarray, shape (N,)
B-spline knots. The knots must have the full endpoint multiplicity. Zero-pad spline coefficients if needed.
Order of the B-spline.
- coeffs_ppndarray, shape (K, P, D)
Coefficients of the piecewise polynomial where K is the order (
order), P is the number of pieces and D is the dimension.
- breaksndarray, shape (P+1,)
Break points of the piecewise polynomial.
