MATLAB function to partition very large graphs very fast. This function implements a graph partitioning algorithm based on spectral factorization. This algorithm is described in the following technical report:
Joã o Hespanha. An efficient MATLAB Algorithm for Graph Partitioning. Technical Report, University of California, Oct. 2004. Available at http://www.ece.ucsb.edu/~hespanha/techrep.html.
This algorithm was extensively used in this paper:
