Stateflow

Using States in Stateflow Charts

Stateflow diagrams react to events by changing states, which are modes of a chart. This section describes how to create and specify a state in your new chart and contains the following topics:

• Creating a State -- Shows you how to draw states in the Stateflow diagram editor with the State drawing tool
• Moving and Resizing States -- Tells you how to move and resize states in the diagram editor
• Creating Substates -- Tells you how to create substates of owning superstates
• Grouping States -- Tells you how to group (and ungroup) states, boxes, and functions for convenience
• Specifying Substate Decomposition -- Tells you how to specify the substate decomposition type (parallel or exclusive) for a state or chart
• Specifying Activation Order for Parallel States -- Tells you how to specify the order of activation for parallel (AND) substates in a state or chart with parallel (AND) decomposition
• Changing State Properties -- Tells you how to change the properties for a state
• Labeling States -- Tells you how to label a state with its name and actions
• Outputting State Activity to Simulink -- Tells you how to output a state's activity as an output port signal on a Stateflow block
