Stateflow

Creating a MATLAB Script of API Commands

In the Quick Start for the Stateflow API section, you created and saved a new model through a series of Stateflow API commands. You can include the same API commands in the following MATLAB script, which allows you to quickly recreate the same model with a single command (>> makeMyModel).

• function makeMyModel
  sfnew;
  rt = sfroot;
  m = rt.find('-isa','Stateflow.Machine');
  chart = m.find('-isa', 'Stateflow.Chart');
  sA = Stateflow.State(chart);
  sA.Name = 'A';
  sA.Position = [45 45 300 150];
  sA1 = Stateflow.State(chart);
  sA1.Name = 'A1';
  sA1.Position = [80 80 90 80];
  sA2 = Stateflow.State(chart);
  sA2.Name = 'A2';
  sA2.Position = [220 80 90 80];
  tA1A2 = Stateflow.Transition(chart);
  tA1A2.Source = sA1;
  tA1A2.Destination = sA2;
  tA1A2.SourceOClock = 3.;
  tA1A2.DestinationOClock = 9.;
  sA11 = Stateflow.State(chart);
  sA11.Name = 'A11';
  sA11.Position = [110 110 35 35];
  tA1A11 = Stateflow.Transition(chart);
  tA1A11.Source = sA1;
  tA1A11.Destination = sA11;
  tA1A11.SourceOClock = 1.;
  tA1A11.DestinationOClock = 1.;
  tA1A2.LabelString = 'E1';
  tA1A11.LabelString = 'E2';
  pos = tA1A2.LabelPosition;
  pos(1) = pos(1)+15;
  tA1A2.LabelPosition = pos;
  dtA = Stateflow.Transition(chart)
  dtA.Destination = sA
  dtA.DestinationOClock = 0
  xsource = sA.Position(1)+sA.Position(3)/2-10
  ysource = sA.Position(2)-20
  dtA.SourceEndPoint = [xsource ysource]
  dtA1 = Stateflow.Transition(chart)
  dtA1.Destination = sA1
  dtA1.DestinationOClock = 0
  xsource = sA1.Position(1)+sA1.Position(3)/2-10
  ysource = sA1.Position(2)-20
  dtA1.SourceEndPoint = [xsource ysource]
