Hi everyone.
I started to look at different linearization techniques like:
-linear interpolation
- spline interpolation
- curve fitting...
Now Iam wondering (and I guess its very stupid) : As polynomials with a degree > 1 are not linear, why can I use them for linearization?
With the method of piecewise linear interpolation its clear. You connect two datapoints with a linear function.
But what about quadratic and cubic splines which are not linear?
Thanks in advance for any help,
Kind regards,
Mike
