Decision Logic

Control flow, combinatorial, and procedural logic for decision-making applications

Create combinatorial flow graphs to model common programming constructs such as if-else statements or while loops by using junctions and transitions. With truth tables you can design your Stateflow® logic in a concise tabular format. MATLAB® functions implement more complicated algorithms in your Stateflow chart.


Chart Implement control logic with finite state machine
Truth Table Represent logical decision-making behavior with conditions, decisions, and actions
