Ford-Fulkerson Algorithm for Max Flow Problem

An Edmonds-Karp implementation to solve the Max-flow Min-cut Problem

See details of the Max-flow problem in http://www.geeksforgeeks.org/ford-fulkerson-algorithm-for-maximum-flow-problem/
The first example in the code (as well as the thumbnail image) is taken from the same website above.

This MATLAB code works with an adjacency matrix to represent the graph. It also contains the function "findpath" which is a BFS (Breadth-first search) implementation for finding augmenting paths. Paths are stored using a predecessor array. I tried to make the code look elegant. :)

The output is the maximum flow and the residual graph.
