Bus-capable blocks are not available in Simulink 5.0 (R13)

Bus-capable blocks have been implemented in Simulink 6.0 (R14). The following blocks are bus-capable:

 Memory
 Merge
 Switch
 Multiport Switch
 Rate Transition
 Unit Delay
 Zero-Order Hold

In previous releases, Simulink software propagated buses only through virtual blocks, such as subsystems inpurts and outports.
