Hello,

I try to increment the name of a component in app designer, in order to create a loop,

hereafter an example:

for i=1:8
app.Lamp.Color_i = [0 0 0]
end

Of course, the above example does not work, I tryed several type of concantenate functions, and also eval function, but I did not succed.

Thanks in advance for any help !

From my understanding, you want to access the uilamp present in the app using app designer.

If uilamps are named as Lamp1, Lamp2, Lamp3 and so on.

Then you can access them using the following statement

for i=1:8
    app.("Lamp"+i).Color = "red";
end

Hope this helps!
