I need help with programming a Depth First Search using Matlab.

I'm working on a sensor networking problem. I have a vector with the index of the nodes (in an n x n matrix) that should be connected. I also have an n x n matrix for the weighted edges between the connected nodes. First I would just like to see if a path exists between a root node and the end. Eventually, I will need to find the shortest path deterministically. Can anybody help with this problem? There was no subtopic area for Matlab programming.

I suppose your problem is similar to finding the minimal path in a graph, so take a look at graph specific algorithms (connectivity and shortest path algorithms), see here for an example:

You can google for more algorithms/details.
