Changing Stateflow parameter from MATLAB

[brfe]

Hello,

Im having a problem to change a Stateflow parameter by using a MATLAB m-file.

I already changed a constant value in Simulink by using the function set_param('obj','data','value'). But when I try to change a Stateflow parameter I recieve an error message telling that in my Stateflow chart there is no parameter with that name.

Does anybody knows how is it called the parameter in Stateflow? Is it possible to do that?

Thanks a lot,
