gaimc : Graph Algorithms In Matlab Code

Efficient pure-Matlab implementations of graph algorithms to complement MatlabBGL's mex functions.

function varargout=load_gaimc_graph(graphname)
% LOAD_GAIMC_GRAPH Loads a graph from the gaimc library
% load_gaimc_graph is a helper function to load a graph provided with the
% library regardless of the current working directory.  
% If it's called without any output arguments, it functions just like a
% load command executed on the .mat file with the graph.  If it's called
% with an output arguemnt, it functions just like a load command with
% output arguments.  It's somewhat complicated to explain because this is
% just a convinence function to make the examples work for any path, and
% not just from the gaimc root directory.
% Example:
%   % equivalent to load('graphs/airports.mat') run from the gaimc directory
%   load_gaimc_graph('airports') 
%   % equivalent to P=load('graphs/kt-7-2.mat') run from the gaimc directory
%   P=load_gaimc_graph('kt-7-2.mat') 
%   % so you don't have to put the path in for examples!
