I have an application with several inputs.

Currently, I input the data manually in the GUI. I want to add a push button and load a txt file that contains numbers, text, etc that goes into these fields.

Examples of the fields and the data:

app.REditField.Value = PEI
app.DEditField.Value = 1.33
app.Slider.Value = 20
% pick one
app.EButton = 0
app.SButton = 0
app.HButton = 1 

I saw some examples with "eval" and "readtable" but they are not variables... Here’s what I have so far (I know it’s not much):

% Button pushed function: LoadDataButton
        function LoadDataButtonPushed(app, event)
            [filename] = uigetfile ({'*txt'});
           
        end

It makes sense. I changed the extension to .m and it works perfectly now. Thank you so much.

By the way, is there a way to encrypt this .m input file so that you can only open it with the app?

Update: I converted to .p file (obfusicated) and it still works in the same way as .m. (I know p-code is not the same thing as encryption).

在 MATLAB Online 中打开

If the extension is already .m or .p then

function LoadDataButtonPushed(app, event)
   [filename, folder] = uigetfile({'*.m', '*.p'});
   if ~ischar(filename); return; end   %user cancel
   filename = fullfile(folder, filename);
   run(filename);
end
