Thank you very much for this package, it is exactly what I'm looking for. I do have one question/comment. In Matlab 2011a, I get a warning that tsearch is going to be retired and to use delaunayTri/pointLocation isntead. I subbed in this set of commands (seemingly appropriately), and I cannot get the code to work correctly. Could you possibly advise on this? I'm going to use the code as is for the time being and try to implement and update. I'm not sure if you would be willing to use this update as a newer revision or are currently working on this problem.
