Thank you for the link.

It is for building extraction from aerial images. After segmentation process boundaries are zigzag-shaped with many intrusions. I would like to simplify polygons but to maintain their essential shape. It means buildings should have orthogonal angles and small extrusions should be cut off. So I am looking for some implementation algorithm in MatLab. Like this: http://img812.imageshack.us/img812/3284/exampleus.png

Hi Anton. I have tried your function.
It works very well.
Do you know about some function like your but
which can simplify and after orthogonalize input set of points?
