Hello, I want to change all the parameter names in stateflow with some script. with the following script I can see the change of parameter name in model explorer:

ChartObj=sfrt.find('-isa','Simulink.BlockDiagram','-and','Name',gcs);

stateChart = ChartObj.find('-isa','Stateflow.Chart');

objArray = stateChart.find('-isa','Stateflow.Data','Scope','Parameter');

set(objArray(i),'Name',new_label);

But the entry in the stateflow still uses the old label name. So when I do ctrl+D, there is error. Can you tell me how to change the entry also with the script? Thanks

在 MATLAB Online 中打开

function SF_RenameParam(ChartName,ParaOldname,ParaNewname)
    
    rt = sfroot;
    m = rt.find('-isa','Simulink.BlockDiagram');
    %ch = m.find('-isa','Stateflow.Chart');
    ch = m.find('-isa','Stateflow.Chart','Name',ChartName);
    %Rename Parameter in workspace 
    chData = ch.find('-isa', 'Stateflow.Data','-and','Name',ParaOldname);
    chData.Name = ParaNewname;
    %Rename Parameter name in stateflow transition label
    ch_transitions = ch.find('-isa','Stateflow.Transition');
    for index=1:length(ch_transitions)
        LabelStr = ch_transitions(index).LabelString;
        if ismember(ParaOldname,LabelStr)
            ch_transitions(index).LabelString = strrep(LabelStr,ParaOldname,ParaNewname);
        end
    end
end
