This example shows how to use the spmak, spcrv, cscvn and rscvn commands from Curve Fitting Toolbox™ to construct spline curves in the plane. In order to determine nerve segment length and curvature, a periodic interpolating cubic spline curve r → (t) was fitted to each segment using the MATLAB Curve Fitting Toolbox function cscvn, with r → (t) = 〈 f (t), g (t), h (t) 〉 in which f (t), g (t), and h (t) are the x, y, and z coordinates of points along a segment. "Natural" or periodic interpolating cubic spline curve (cscvn) allows me to fit an interpolating spline curve that passes all the control points.
