Create Charts by Using a MATLAB Script - MATLAB & Simulink (original) (raw)
Main Content
This example shows how to include Stateflow® API commands in a MATLAB® function or script. Creating a script of API commands allows you to avoid repetitive chart creation steps and recreate the same model with a single command. For more information, see Overview of the Stateflow API.
Run the MATLAB Function
The function makeMyModel, which is defined at the bottom of this page, produces a "base" Stateflow chart that you can reuse as a template for your applications.
ch = makeMyModel; view(ch)
Create Base Chart Function
This function creates a Stateflow chart and returns the corresponding Stateflow.Chart object.
function ch = makeMyModel
Create model and access new Stateflow.Chart object.
rt = sfroot;
prev_machines = find(rt,"-isa","Stateflow.Machine");
sfnew;
curr_machines = find(rt,"-isa","Stateflow.Machine");
m = setdiff(curr_machines,prev_machines);
ch = find(m,"-isa","Stateflow.Chart");Create state A in chart.
sA = Stateflow.State(ch);
sA.Name = "A";
sA.Position = [50 50 310 200];Create state A1 inside of state A.
sA1 = Stateflow.State(ch);
sA1.Name = "A1";
sA1.Position = [80 120 90 60];Create state A2 inside of state A.
sA2 = Stateflow.State(ch);
sA2.Name = "A2";
sA2.Position = [240 120 90 60];Create transition from A1 to A2.
tA1A2 = Stateflow.Transition(ch);
tA1A2.Source = sA1;
tA1A2.Destination = sA2;
tA1A2.SourceOClock = 3;
tA1A2.DestinationOClock = 9; Add default transition to state A.
dtA = Stateflow.Transition(ch);
dtA.Destination = sA;
dtA.DestinationOClock = 0;
dtA.SourceEndPoint = dtA.DestinationEndpoint-[0 30];
dtA.MidPoint = dtA.DestinationEndpoint-[0 15];Add default transition to state A1.
dtA1 = Stateflow.Transition(ch);
dtA1.Destination = sA1;
dtA1.DestinationOClock = 0;
dtA1.SourceEndPoint = dtA1.DestinationEndpoint-[0 30];
dtA1.MidPoint = dtA1.DestinationEndpoint-[0 15];end
