MATLAB program for Arc Length Method for the arch problem given in M A Crisfeild.

If an interpolating curve follows very closely to the data polygon, the length of the curve segment between two adjacent data points would be very close to the length of the chord of these two data points, and the length of the interpolating curve wo
