Hi,
To check if an EditText in a MATLAB GUI is empty and show a warning message if it is, you can use the following steps -
  • Get the text using get function
  • Check if the text is empty or not
text = get(handles.editText, 'String');
if isempty(text)
% Show the warning
else
% Proceed with the program
end
