push_relabel_max_flow.m

function [varargout]=push_relabel_max_flow(A,u,v,varargin)
% PUSH_RELABEL_MAX_FLOW Goldberg's push-relabel max flow algorithm
%
% This function calls Boost's implementation of Goldberg's push relabel
% algorithm to compute a maximum flow in a graph.
%
% See the max_flow function for calling information and return parameters.
% This function just calls max_flow(...,struct('algname','push_relabel'));
%
% Example:
%   load('graphs/max_flow_example.mat');
%   push_relabel_max_flow(A,1,8)
