Hi!

I am wondering if there is any good way to access component with a string variable. Let me give an example.

I got an array of strings and want to loop through them to access value of every component.

components = ["componentName1", "componentName2", "componentName3", ... ]

for i = 1:length(components)

value = app.components(1, i).Value

end

To clarify component(1, i) is a string and not an object inside of app, however the string has the name of that component.

I appreciate any help I can get!

See Generate field names from variables which also applies to class properties.

for i = 1:numel(components)  %prefer numel to length
    value = app.(Components(i)).Value;   %prefer 1D indexing with vectors
    %..
end

It worked! Thank you very much!
