nodes_data_structure — description of the data structure representing the nodes of a graph
A nodes data structure is represented by a Scilab mlist
with type nodes
and 3 fields:
number
the number of nodes.

> A Scilab mlist
data structure of type ngraphic
which stores the information relative to nodes display (see ngraphic_data_structure
data
A Scilab mlist
data structure of type
nodedata
. which stores the data associated with
nodes. By defaut this data structure is empty. User can add
its own fields using the add_node_data
function..
For a given field the associated data should be a row vector or a matrix. In the matrix case a column is associated to a node.
