annotate +util/plotf.m @ 86:3c39dd714fb6

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
In Curve: Added numerical FD differentiation if derivative is not supplied. Added arc length computation based on the derivative. Added arc length parameterization (but this function is very slow.). In +util: Added fzero_vec.m and integral_vec.m, which call fzero and integral but take vector arguments.
