Declaring Variable-Size Inputs and Outputs

1. In the Stateflow Editor, select Add > Data > Input from Simulink or Add > Data > Output to Simulink.

   The Data properties dialog box opens.

2. Select the Variable size check box.

3. Set Scope as Input or Output.

4. Enter size:

   Data	What to Specify
   Input	Enter -1 to inherit size from Simulink or specify the explicit size and upper bound. For example, enter [2 4] to specify a 2-D matrix where the upper bounds are 2 for the first dimension and 4 for the second.
   Output	Specify the explicit size and upper bound.

   For example:
