09 Nov 2011	Katherine Ellis	Hi Bruno, I have downloaded your cunwrap function and wanted to run test_cunwrap first before I tried the function. However I get the error:- CUNWRAP: cannot detect network flow (LP) engine Why does this arise and how can I fix it? Is there some extra toolbox I need installed? (NB-I am using a student lisence) Thanks, Katherine Ellis
09 Nov 2011	Bruno Luong	Katherine, you need the optimization toolbox, especially linprog()
07 May 2012	leila hell	hello, in fact i m using your unwrapping code and it works perfectly but the fact is that i didn't understand how does it work. it would me very nice of you if you can help me to understand it .
07 May 2012	Bruno Luong	To leia, the technique is described in Costantini, M., 1996: A Phase Unwrapping Method Based on Network Programming, Proceedings of the "Fringe ‘96" Workshop, Zurich, Switzerland, 1996, ESA SP-406
