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