### arclength - File Exchange - MATLAB Central

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.
