Finding the length of curve using MATLAB. As per integral calculus, the length of a continuous and differentiable curve f(x) from x=a to x=b is given by. S= Now how do we find the length of a curve in MATLAB. Let us do this via an example. Assume one asked you to find the length of from Π to 2Π. In the book, How People Learn, the authors …
The arc length formula says the length of the curve is the integral of the norm of the derivatives of the parameterized equations. ∫ 0 3 π 4 cos 2 (2 t) + sin 2 (t) + 1 d t. Define the integrand as an anonymous function.
Editor's Note: This file was selected as MATLAB Central Pick of the Week The arclength function computes the length of a general space curve. This is not too difficult if the curve is assumed to be piecewise linear (a one liner) but if the curve is to be a smoothly interpolated spline, then the problem becomes more difficult.

A call to diff(Xq) shows that we are moving in steps of constant arc length along $\gamma $, while a call to diff(Vq) shows that the time steps are no longer equal (first column). Thus, the result of our interpolation is:
