function bnet = bnet_from_engine(engine)% BNET_FROM_ENGINE Return the bnet structure stored inside the engine (inf_engine)% bnet = bnet_from_engine(engine)bnet = engine.bnet;% We cannot write 'engine.bnet' without writing a 'subsref' function,% since engine is an object with private parts.% The bnet field should be the only thing external users of the engine should need access to.% We do not pass bnet as a separate argument, since it could get out of synch with the one% encoded inside the engine.
