set of nodes from a path
ns = path_2_nodes(p,g)
row vector of integer numbers of the arcs of the path
row vector of integer numbers of the set of nodes
path_2_nodes
returns the set of nodes ns
corresponding to the
path p
given by its arc numbers ; if p
is not a path, the
empty vector []
is returned.
