MATLAB: What is a differece between a constant and Paremeter in Model simulation

simulationsimulinkstateflow

what is the differene between constants and parameters in stateflow ?
Why are these two different objects used , when one can serve the purpose ?
are there any specific use ? like when to use parameter and when to use constant ?

Best Answer

Do you mean that a Parameter can serve as a Constant? I think a Constant is still needed because it's value doesn't change during simulation and can be inlined into the C code generated for the Stateflow chart, without needing to read it from the workspace (like you might need to do for a Parameter, especially in case of a tunable parameter which can change during simulation). So if you are using a constant value which doesn't change, it is might be more optimal to declare it as a constant.
