I need to develop a spline for a repeating function. Here are the requirements:
- spline must is for a repeating function, repeating every 2 PI.
- The spline must be continuous for position and first derivative, including the repeating point 0, 2 PI.
- A segment of the spline must be perfectly linear. The segments before and after must begin/end with the same derivative.
Any help would be appreciated.
