Have we got any hardcore maths people on here?
Anyone know if Cubic Interpolation is the same as Cubic Spline Interpolation?
Need to familiarise myself with the latter for work.
Just watched this but not sure if it's the same thing?

Never heard of cubic interpolation tbh.
Spline interpolation is just applying lower order polynomials to subsets of data points as higher order polynomials introduce erroneous results. Cubic spline interpolation = using 3rd order polynomials to connect each pair of data points.
Dunno if that helps / sounds what you're meant to be looking at?

I've actually watched a few of that guy's videos and TBH I think they are quite good.

Hold up, dug out a maths book. No, not the same it seems.

Maths is rusty as hell regarding interpolation but id recommend you having a look on physicsforums.com; has helped me loads in the past.

I'm being over-critical because I'm not well up on it. But he spent time explaining algebraic substitutions and percentage error in the approximations, but not some of the more difficult concepts. Guess it helps to have already had some exposure to it.
