#DEGREE DISTRIBUTION CALCULATION TOOL MANUAL#

graph_complement.m - the complement graph.tarjan.m - find the strongly connected components in a directed graph.giant_component.m - extract the giant component only (undirected graph).find_conn_comp.m - the number of connected components in an undirected graph.num_conn_comp.m - number of connected components (using algebraic connectivity).average_degree.m - the average degree (# links) across all nodes.multiedges.m - number of arcs (i,j) with multiple edges across them.selfloops.m - number of selfloops, i.e.link_density.m - the density of links of the graph.numedges.m - number of edges/links in the network.numnodes.m - number of vertices/nodes in the network.getEdges.m - return the list of edges for varying graph representations.getNodes.m - return the list of nodes for varying graph representations.The code is classified by functionality as follows (121 routines total, last version Nov 6, 2011).

The Octave toolbox also includes a manual with background information and examples. All functions are generally better documented. Some parts of the code are restructured and updated. The new and current version of this code is available in Octave (GNU Octave Version 3.4.0 and Gnuplot 4.2.5) here. The license text is also available at the end of this page. This code is published under the BSD license. No code is perfect so please contact gergana at alum dot mit.edu if you notice errors or have pointers to better routines. Different authorship is indicated in the header. There is some overlap with the grTheory toolbox and the MatlabBGL library published on Matlab Central. The code is not object-oriented, and should be easy to use, read and improve upon. These routines are useful for someone who wants to start hands-on work with networks fairly quickly, explore simple graph statistics, distributions, simple visualization and compute common network theory metrics. The last version, posted here, is from November 2011.
