Fitting curve


I am working on my Ph.D. thesis about sharp feature detection and visualization.

As for the visualization, I am using algorithm based on this example

The curve fitting algorithm is working fine but I would like to estimate the approximation error for the final curve.

For example. I set the number of control points to 80, the curve is calculated and I want to estimate the mean or max error from the data to the curve. Is there any way to estimate it?

Thank you
With regards
