You can use "uialert" with a try/catch block to catch and display the MATLAB error message in a pop-up dialog box.

Refer to the following documentation for more info on "uialert":

For example, the following code will show a pop-up dialog titled "Unable to connect to target" and displays the full MATLAB error message. By setting the interpreter to HTML, even hyperlinks are enabled:

try
    % enter code
catch ME
    uialert(app.UIFigure,ME.message,"Unable to connect to target","Interpreter","html");
end
