How can i call a state machine which is inside a function.Function is called iteratively?

Hi ,

I want to call a function inside a loop. The function has a Statemachine in it.

Below is the Pseudo "C" code for which the equivalent stateflow model is required.

for(i=0;i<2;i++)

{

      CallStatechart(i);

}

CallStatechart(j)

{

      case A:......out[i]=...;
      case B:......out[i] =...;
      case C:......out[i] =...;
  }

State machines in C are usually more like

current_state = 0;
for (i=0; i<2; i++)
{
   current_state = CallStatechart(current_state, i);
}

int CallStatechart(int current_state, int statenum)
{
  switch(current_state)
  {
    case A: ....; new_state = ...; break
    case B: ....; new_state = ....; break;
    ...
  }
  return new_state;
}

This permits reactions to be conditional on the current state, and permits the state to be changed in non-linear ways.

My question is to know if we can have statemachine inside a function.If i am doing it, i am getting an error saying :

"Function 'Fun' contains substate 'A'. This is not allowed"

Hi,

This requirement can be achieved by implementing the statemachine inside the "For Iterator Subsystem" in simulink. Please refer to the attachment.

Thanks.
