Variables in the Model (Using the Communications Blockset)

Communications Blockset

Variables in the Model

Loading this model automatically defines in the MATLAB workspace five variables that are used in the demo's blocks and subsystems. To clarify the discussion of the individual blocks and subsystems, the variables' meanings and values are listed in the table below:
