spline_pl(x,y,k) - a Matlab program to compare different parametrizations of parametric cubic splines.

Here x,y – data points, k – parameter of parametrization: k=0 – uniform, k=1 – chord length, k=0.5 – centripetal parametrization.

Examples of data points:

left_hand.mat

angle.mat

four_points.mat
