| Version | Published | Release Notes | Action |
|---|---|---|---|
| 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 |
