subgraph - subgraph of a graph
8
v : row vector, numbers of nodes or edges
11
: string, 'nodes' or 'edges'
15
g1 : graph list of the new graph
18
subgraph returns the graph g1, built with the numbers given by the the
19
row vector v. If ind is the string 'nodes', g1 is built with the node
20
numbers given by v and the connected edges of these nodes in g. If ind
21
is the string 'edges', g1 is built with the edge numbers given by v and
22
the tail-head nodes of these edges in g. All the characteristics of the
23
old nodes and edges of g are preserved.
