Stateflow for Complex Logic When to use Stateflow?Model instantaneouschanges in dynamicsystems– Changes in state– Events Finite state machinesFlow diagrams9
Stateflow Overview Extend Simulink with a design environment fordeveloping state machines and flow chartsDesign systems containing control, supervisory, andmode logicDescribe logic in a natural and understandable formwith deterministic execution semantics10
Stateflow: Key Features Defines functions– Procedurally, using MATLAB– Graphically, using flow diagrams– In tabular form, with truth tablesProvides language elements,hierarchy, and parallelismAnimates Stateflow chartsIncorporates custom and legacy CcodePerforms static and run-time checks11
ConclusionsSimulink and Stateflow provide: A powerful environment for modelling real processes. in a modular fashion. and are fully integrated with the MATLAB environmentfor extensive design & analysis capability12

orthogonal states active at the same time. Stateflow uses a variant of the finite state Notations A notation defines a set of objects and the rules that govern the relationships between those objects. Stateflow notation provides a common language to communicate the design information conveyed by a Stateflow diagram. Semantics
Albert Woodfox, 68, has been in solitary confinement since his conviction in 1972 for the murder of a prison guard. He has always maintained his innocence. There is no physical evidence to link him to the crime; the conviction relied pri-marily on the testimony of an eye witness who received favours, including his re- lease, for cooperation. Albert’s conviction has been overturned three .
