mat_2_graph(1) Scilab function mat_2_graph(1)
NAME
mat_2_graph - graph from node-arc or node-node incidence matrix
CALLING SEQUENCE
g = mat_2_graph(a,directed,[mat])
PARAMETERS
a : sparse node-arc or node-node incidence matrix
directed : integer, 0 (undirected graph) or 1 (directed graph)
mat : optional string, 'node-arc' or 'node-node' matrix
g : graph list
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 argu-
ment mat is omitted or is the string
EXAMPLE
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');
