Hello everybody,
I have a simulink project which at certain times (not constant periods of time) generates an array of inputs I want to send to a stateflow chart.
the data is an array as follows:
[scenario_1, data_size_1,data_1,scenario_2, data_size_2,data_2].
where scenarios 1 and 2 are scalars, data_size 1 and 2 are scalars the states the following data length, and data 1 and 2 are vectors size: [data_size_m,1], where data_size_1~= data_size_2.
I first split the array into two different arrays, and then send them into the stateflow chart.
My question is how can I activate the stateflow chart only when a new input arrives?

Two options.
  1. You can use an event to trigger the statechart. In this case you will need Simulink logic to determine when the data is new/changed and then trigger the statechart.
  2. Second option is to use the hasChanged() stateflow function to determine when your data has changed inside the state chart.
