associates new data fields to the edges data structure of a graph
g = add_edge_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 edges. This parameter is optional. If it is omitted the data field is set to []
.
g = add_edge_data(g,name [,value])
associates the
data fields named name
to the edges 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
i
th column is associated with thei
th
edge.
