Plots the contours of a function defined on an unstructured triangular grid directly, without the need to interpolate back onto a Cartesian array.
I have attempted to replicate much of the functionality of the regular "contour" function.
Type "help tricontour"
Type "contourdemo" for some examples
You may also find my mesh generator "mesh2d.m" in the physics and Chem section helpful.
UPDATE 11/05/2006
- Can now be used with clabel
- A bit faster
UPDATE 15/05/2006
- Much more accurate (now uses quadratic interpolation)
