Yes. Wrap your code in a try catch block. Here is the snippet:
try
% Some code that might generate an error.
catch ME
errorMessage = sprintf('Error in function %s() at line %d.\n\nError Message:\n%s', ...
ME.stack(1).name, ME.stack(1).line, ME.message);
fprintf(1, '%s\n', errorMessage); % Print to command window.
uiwait(warndlg(errorMessage)); % Popup message alert to user.
end
