Hey Samuel,
In order to create a save button in a MATLAB app to save inputs and outputs to a text file, you can make use of callback functions in App designer. Here is a simple way to create callbacks in App Designer:
function codeButtonResponse
fig = uifigure('Position',[500 500 300 200]);
btn = uibutton(fig,'ButtonPushedFcn',@buttonCallback);
function buttonCallback(src,event)
disp('Button pressed');
% Your code to retreive the desired variables and save in a file
end
end
Once you create a simple callback function, all you have to do is access the variables you wish to save and store them in a file, for example a .MAT file.
You can access the input and output fields to get the desired values and save them in a file, for example:
a = app.editfield1.Value;
b = app.editfield2.Value;
save('pathtomat.mat','a','b');
I hope this would give you some hints to create a save button in your app.
