Installing and running matlab app able to load and process .mat file

Good afternoon to everybody. With Matlab compiler (AppDesigner) I have to create a standalone app able to use a given .mat file for plot data.

This .mat file contains structures with cells, neural network models, linear models (from fitlm), tables, double arrays.

I have to plot both the data contained in the double arrays and the data (double arrays) generated after calling the neural network models, as here below e.g. listed.

To import the .mat file I have created a property with "load" from a given path.

When I run the application in AppDesigner, the app works correctly.

When I install the packaged standalone application with the inclusion of the .mat file to load and I run it, the standalone app don't works. I need some help!

Thank you and best regards.

    properties (Access = public)
       var = load ('*path\file.mat') % Description
    end
    
    [...]
        
    n = app.var.net;
    t = app.var.table;
    x = n(app.var.FirstArray);
    y = app.var.SecondArray;
    scatter(app.UIAxes,x,y,"black");

I am facing almost similar situation. I have .csv file to be processed and plot the figures. When I run the app in standalone application it can process data only which are in Desktop (Same directory where my app shortcut is located). I want that my app will be able to process any data from any directory (any directory from my pc or from removeable disk /usb). Would you please suggest me how to do that ? @Matteo Bellini@J.

If the problem is that the standalone app can't find the file to load in the first place, you need to understand how paths work in deployed apps.

Or use full paths
