transition = Stateflow.Transition(ch);
transition.Source = [];% this makes it default transition.
transition.Destination = j2;
transition.LabelString = '{xx;yy;zz;}';

[Fangjun Jiang]

sfnew
rt = sfroot;
ch = find(rt,'-isa','Stateflow.Chart');
st = Stateflow.State(ch);
view(st)
j1 = Stateflow.Junction(ch);
j1.Position.Radius = 16.18;
j1.Position.Center = [31.41 27.18];
j2 = Stateflow.Junction(ch);
j2.Position.Radius = 16.18;
j2.Position.Center = [62.41 27.18];
transition = Stateflow.Transition(ch);
transition.Source = j1;
transition.Destination = j2;
transition.LabelString = '{xx;yy;zz;}';

thanks, i have anothewr question :

the transition label shows:{VehicleModesCoordinatorDfr;VehicleStartManagerDfr;GearSelectionDfr;DriveModeSelectionDfr;}

but i want it changed to following format(split to several lines), how to do

{VehicleModesCoordinatorDfr;

VehicleStartManagerDfr;

GearSelectionDfr;

DriveModeSelectionDfr;}

[Fangjun Jiang]

Manually make it that way and read it back to see if there is any difference. I suspect some characters like newline() or char(10).

[Fangjun Jiang]

It is char(10) or newline();

transition.LabelString = ['{xx;',newline,'yy;',newline,'zz;}'];
