Detailed Description
Wrapper to the pspline library, making it easier to use for 1-D applications where speed is not the main priority. If spline representations are to be reused, manually use the library.
Order 1 (linear), 2 (akima hermite) or 3 (cubic) possible. Boundary conditions are possible:
- -1: periodic
- 0: not-a-knot
- 1: prescribe first derivative
- 2: prescribe second derivative
However, for order 2 boundary condition 2 is not available and for order 1 none of them.
Furthermore, derivatives can be specified:
- up to 1 for order 1 and 2
- up to 2 for order 3
Finally, extrapolation can be performed as well.
