(* Major performance improvements when using the network blocks. The simulation time is now linear rather than exponential in the simulated time. [The poor performance in previous versions was due to Matlab s memory management.] * Two new Simulink blocks added, making it easier to develop networked applications. The two blocks makes it possible to send and receive network messages without using kernel blocks and code functions. A related new)
