Hi, I am creating an app. In this app there is a checkbox for every car. There are 10 cars so I changed each box name as
app.CalculatePlmCheckBoxC1
app.CalculatePlmCheckBoxC2
...
And after this I want to assign the value of these boxes to certain variables. My code is below, but it doesn't work. and I can't solve the problem.
for numOfCars = 1:1:10
calculatePlmApp = sprintf('app.CalculatePlmCheckBoxC%.Value',numOfCars);
varValue = eval(calculatePlmApp);
newName = sprintf('PlmC%d',numOfCars);
assignin('base',newName,)varValue;
end
I would reallyappreciate it if you could help. Thank you already!

Replace the anti-pattern, evil, obfuscated EVAL-based code with this simpler, efficient code:
F = sprintf('CalculatePlmCheckBoxC%d',numOfCars);
V = app.(F).Value
Note that magically making variables appear in other workspace is slow, complex, and inefficient.
Note that numbering variables like that makes processing your data more complex then if you used basic indexing.
Is there a particular reason why you cannot process that data within the GUI ?

Hi, yes this app is requested from me and I need to create an app. Thank you. There is a syntax that I can't break, they use it in my workplace. So I am kinda forced to work this way. I am new at app designing , I didn't know this type of calling variables.
