add_node_data — associates new data fields to the nodes data structure of a graph
g = add_node_data(g,name [,value])
a graph data structure (see graph_data_structure )
a character string, the name of the data field.
a row vector or a matrix with column size equal to the number of nodes. This parameter is optional. If it is omitted the data field is set to [].
g = add_node_data(g,name [,value]) associates the
data fields named name to the nodes data structure
of the graph g and assign it the value given by the
parameter value. If the last argument is not given
the empty matrix [] is assigned.
value can be a matrix of any type. The
ith column is associated with theith
node.
