annotate cell2vector.m @ 87:0a29a60e0b21

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
In Curve: Rearranged for speed. arc_length_fun is now a property of Curve. If it is not supplied, it is computed via the derivative and spline fitting. Switching to the arc length parameterization is much faster now. The new stuff can be tested with testArcLength.m (which should be deleted after that).
