Stateflow

Exporting Graphical Functions

You can export a chart's root-level graphical functions to the chart's model. Exporting a chart's functions extends their scope to include all other charts in the same model.

You can also export graphical functions in library charts to a model as long as the library charts are present in the model. To export a chart's root-level functions, select Export Chart Level Functions on the chart's Chart Properties dialog box (see Specifying Chart Properties).

In the following example, the model main_model has two library stateflow charts, lib1Chart and lib2Chart:

Both lib1Chart and lib2Chart were dragged into the model main_model from the library models lib1 and lib2 in which they were created. In the properties dialog for all three charts, the Export Chart Level Functions option is selected. Each chart now defines a graphical function that can be called by any other chart placed in main_model.

The sequence of action in simulation of main_model is as follows:

• The chart modChart calls the graphical function lib1_func, with the two arguments, x and y.
• lib1_func calls the graphical function lib2_func, passing the same two arguments.
• lib2_func calls the graphical function mod_func, which adds x and y.
• The result of the addition is assigned to x.
