Hi,
If our/your concepts has state based, then we should use stateflow otherwise wil use simulink.
For example, In car, Gear box, CD player platforms will be desigend in stateflow, because that will work on state based. These type of platfoms doesn't have any mathematical calcuation, so we can't implement in simulink.
To solve the mathematical related, we shoud use simulink, at that time, stateflow will not help us to do.
