I have a question about app designer. I would like make an interface that launches my Matlab script and that this script reads the values of two parameters. I have declared these two variables (A and B for example) in properties in public acces. I use a spinner to define the value of A and B.
In the Spinner function I update the variable this way :
app.A = app.ASpinner.Value;
In my MATLAB script I wanted to use this value for different equations. So I called it that way :
Interface.A; Where Interface is the name of my app designer project.
But I have this error :
ActiveX - invalid PROGID 'A'; Error Code = 800401F3
I instantiated these two variables with a value in the startupFcn function.
So my question is whether it's possible to have a variable coming from an app designer interface in a matlab script.
I can go through a .mat file for this but is ther a more direct method?
Thanks in advance for your help, have a nice day.

If you want to be able to access your app inside the script, first create and assign your app to a variable, then you can access its properties.
app = Interface; % this will launch your app.
A = app.A; % now you can get its properties.
