How do i debug a problem from app designer in the automatic part?

Hi,

So, i have created an app on App Designer in Matlab, and i am struggling with a problem with the automatic transcription of the design view into the code view. I putted some radio buttons on my design view, then i added a callback for the moment where someone push the 'go' button. And everything seems ok to me but there is only this red advertissment that i can get rid of because i cannot write in this place.

Is there someone who has an explanation or a solution to propose?

(i can put more pictures if you want)

Hi Clement,

You are probably missing or have an extra end statement somewhere in your code.

If you click on function or method, the program will show you which end statement terminates the block.

Thank you for your answer,

I guess there is a problem with my callback then because it works when i don't use it in my code. What I want is to transfer the answer of my form in a text file.

            fclose(fid)
            
            %system('matlab post_processing.m');
        end
            end
            

Is there something wrong in it? I just test every answer to know which one they choose ans I want to keep them and send them to another program.

sorry for the french in it, its not relevant, it is just names.

Yes,

all your if statements need to be terminated with end. Please see the documentation on how to write the code properly.

fid=fopen('Valeur_App.txt','w');
%ReactionMat Radio button
if (app.ElastiqueButton.Value==true)
    fprintf(fid,'1')
elseif (app.PlastiqueButton.Value==true)
    fprintf(fid,'2')
elseif (app.LesdeuxButton.Value==true)
    fprintf(fid,'3')
end

You can solve your problem easier, radio button group has the property SelectedObject that tells you which button is selected.

The line below will return the button object, you can use its text property to detect which button is it.

app.ReactionMat.SelectedObject
app.ReactionMat.SelectedObject.Text

Oh yes thank you,

i was writing as in python,

All right, yes thank you i will try that :)

have a good day
