Retrieve an attribute from matlab to app designer

Hello !

I have a matlab script with some attributes and an App designer script.

I would like to know if it is possible to use or to retrieve an attribute of the matlab script with the appdesigner script.

My goal is to compare an attribute's value with 0 and launch the script or not ?

Thanks for helping !

There is several ways to do what you want to do. It will depend on your MATLAB knwoledge.

To answer you first question. You can access a property of any object (not only an app) if this property is a Public one (you can access Private property only in the method of that class).

I don't know your app so if several cause can set your proeprties to 0, I suggest you use events (advance MATLAB behavior but very powerfull).

If ther eis only one location in your app where this property is set to 0 then just call your script in your app after verifying the attribute is equal to 0

ok thanks ! The only way that my attribute is equal to 0 is if the user chose a wrong file (i am parsing xml file and so if it's not an XML format my attribute will be equal to 0)

in my matlab script i have

n_component = numel( component_list );

so to use it in app designer i can do

if n_component == 0
    do something
end

as both file are in the same workspace or i have to do

if parsingXML().n_component == 0
    do something
end

? (parsingXML is my matlab script)

I don't know what parsingXML() is.

If your first answer works, use it
