03 Oct 2010	Polygon Clipper Given two arbitrary polygons, the routine calculates the resulting polygon ... Author: Sebastian Hölz	To be honest, this is a really waste of time. This programm is tested on windows XP with matlab 2008b, MAC and Linux with matlab 2009. They are all having the same error as I have put out in the last post. Users be aware of this. After 2 days of trying to fix this problem, I am now give up and have to look for an alternative programme. I am not sure if the author check these posts or not. If you do, I could send you my programe for your debugging. Thanks. Lian
01 Oct 2010	Polygon Clipper Given two arbitrary polygons, the routine calculates the resulting polygon ... Author: Sebastian Hölz	Dear Sebastian Hölz: Hi, these programmes are very handy. However, I have got this error after calling the mex function repeatedly. there might be a memory leak in the code. Thanks.
