nodedatafields — returns the vector of node data fields names
F = nodedatafields(g)
a graph data structure (see graph_data_structure )
a row vector of strings. Each element is a field name of the nodes data data structure.
It is possible to associate data to the nodes of a graph. This
can be done with the add_node_data function. the
nodedatafields function allows to retreive the field
names of these data. A given node data can be referenced by its field name
g.nodes.data(field_name).
