I have designed a state machine in stateflow. it consists of several variable and states. however, when I am generating codeusing embedded Coder, multiple states and variables are missing from code. on clicking on that particlar state, Stateflow prompts "Stateflow object eliminated by optimization". kindly suggest how to ensure all states and variables are present in the final code as they are in state machine

To prevent elimination of states or other blocks from generated code by optimization, you need to uncheck Block reduction parameter from Model Configuration Parameters > Simulation Target > Advanced parameters > Block reduction.
