Hi everyone,

New to Matlab app designer. I have trained an ANN model in Matlab. I want to develop a simple app (for possible deployment) using Matlab app designer. The app will have the following features

'Load data' button to load data
Button that says 'Predict'. The loaded data will be predicted on the ANN model I have already trained
a 'Result' interface that will display the predicted value with a unit in mL
An 'Export' button that can export or save the result to an excel file.

I am not sure how to go about building an app with the features I have listed above and the codes that comes with it. Any example code or work will be truly appreciated!

Thanks!

Hello there,

To create an app in MATLAB App Designer with the features you want, you can follow these steps.

First, type "appdesigner" in the MATLAB command window to open App designer and then create a blank new app.

Then, in the App designer's design interface, you can easily add the components that you want by dragging them from the menu.

In your case, you can add

Three "Button" components ("Load data", "Predict" and "Export")
A "TextArea" componenet to display the predicted value with the unit.

You can arrange the components as desired by clicking on them and dragging in the "Design" tab.

You can then add callbacks for each button to perform the desired actions.

For the "Load data" button, the callback function might look something like this:

function LoadDataButtonPushed(app, event)
    % Select and load data
    [file, path] = uigetfile('*.mat', 'Select the data file');
    if ~isequal(file, 0)
        app.data = load(fullfile(path, file));
    end
end
