What difficulty did you encounter in using the code from the file exchange? http://www.mathworks.co.uk/matlabcentral/answers/121067-is-it-possible-to-apply-skeletonisation-to-voronoi

I just copied the entire file and tried with my code. In the first line i got an error stating that function definitions are not permitted at the prompta or scripts..

Use the download button. That will download a .zip that you can then expand into a new directory. Use MATLAB's pathtool to add that directory to your MATLAB path. You can then call upon the function.

This is the work I have done so far.

MATLAB already has a form of qhull available. See

http://www.mathworks.com/help/matlab/ref/convhulln.html

But if you prefer to be sure, download qhull and install it.

You've given me nothing to work with. No images. No code. How can I help you?
