see "Bug in Graph.matching" thread on sage-devel:
{{{
sage: sage: g = graphs.PathGraph(3) # an unweighted graph
sage: sage: g.matching(value_only=True, use_edge_labels=True)
1.0
sage: sage: g.matching(value_only=True, use_edge_labels=False)
2
}}}
as mentioned there, the bug is in the line {{{return Integer(len(d))}}}
near line 6786 in {{{sage/graphs/generic_graph.py}}}.
It should be {{{return Integer(len(d)/2)}}}
