Version Published Release Notes
1.3.0.0

The s-coordinate is no longer normalised, but uses distance units. This is consistent with Merwade's description of the method. (Thanks to Chad Greene for raising this issue)
1.2.0.0

Dramatically increased performance by using a piecewise linear approximation for the smoothed centerline.
1.1.0.0

Added check for a bug in "distance2curve.m"
1.0.0.0
