What is the distribution of points? Do you have an equation for the curve?

Thanks for your reply, I have no equations yet. The picture below is the coordinates of the points and has not been fitted yet.

If you don't have the equation, then use a non-parametric curve fitting: https://www.mathworks.com/help/curvefit/nonparametric-fitting.html, especially see the smoothing splines. This requires the curve fitting toolbox.
