@Javier Montoya: This is an implementation of the undirected version of Yen's algorithm. I would suspect that several changes will be needed to make it directed; the line you mentioned should probably be deleted, among other alterations.

@Qiu: What do you mean by "not intact"?

07 Apr 2011 Boxplot rotate labels, change fontsize This script shows how to rotate labels and change their fontsize with boxplots Author: Peter Mangold

Thank you, this saved me the time needed to hack the solution myself. The examples are clear and straight forward.

@El-ad David Amir, I guess, that you're considering the sG sparse graph as being undirected (symmetric), right?
In case of directed graph, then following line should not be used, right
=> k_G( j_next_node, i_node ) = 0; ?

@El-ad David Amir, By symmetric graphs I was referring to undirected graphs ;-)

@El-ad David Amir
Some function ur script used is missing in my matlab, I thought is a intact, but now, I fix the problem. Sorry for the misunderstanding, thanks for your reply.
