Parameters

Description

mat_2_graph computes the graph g corresponding to the node-arc or the node-node incidence matrix a. Note that a checking is made to insure that a is a sparse node-arc or node-node incidence matrix of a directed (directed = 1) or undirected (directed = 0) graph. If the optional argument mat is omitted or is the string 'node-arc', a must be a node-arc matrix. If mat is the string 'node-node', a must be a node-node matrix.

Examples

g=load_graph(SCI+'/demos/metanet/colored');
show_graph(g);
a=graph_2_mat(g);
g1=mat_2_graph(a,1);
g1('node_x')=g('node_x'); g1('node_y')=g('node_y');
show_graph(g1,'new');
a=graph_2_mat(g,'node-node');
g1=mat_2_graph(a,1,'node-node');
g1('node_x')=g('node_x'); g1('node_y')=g('node_y');
show_graph(g1,'new');
