I couldn't find spline interpolation in groops. How can I perform curve interpolation? I can import the eigen library. But the coding style is quite different. Could you please let me know how you handle this? Thank you.

Hi,
Sorry, your question is unfortunately very unspecifically formulated. Do you want to implement a new method in instrumentResample? In this case, you must write a new class/file in source/classes/interpolatorTimeSeries and include it in source/classes/interpolatorTimeSeries/interpolatorTimeSeries.cpp.

Thank you for your reply! I just want to know how spline interpolation is done in groops and if there is an existing implementation available.
