MATLAB: Is there a way to catch errors with out using try catch statements

error handlingguitry/catch

Hi,

I have created a GUI and deployed it. It works well but sometimes it gives error but user can't see it. Is there a way to show any kind of error to the user by using message box?

In other words I want to catch all errors with out using try catch statements because I have lots of functions in my program and writing try catch for all of them is time consuming.

No, writing TRY-CATCH blocks is not time-consuming. It is required to catch errors and of course you cannot catch all problems automagically.

A reliable program requires an error handling and at least including the main function should be the absolut minimum.

If you take a look at the documentation, you can see that catch ME stores the exception (all error information) in the variable ME. This can be useful if there are multiple errors that you expect to occur, so you can vary your response based on information like the error ID.

You will also need the exception if you want to throw, rethrow or throwascaller.

The ability to throw an empty MException object using THROW, RETHROW and THROWASCALLER is not available in MATLAB. To work around this issue, use a condition statement to bypass the use of an empty MException Object:

errobj = MyIsEqual(params)
if isempty(errobj)
  % do nothing
else
  throwAsCaller(errobj)
end

Using condition statements whenever an empty MException object is given, however, may affect the conciseness of the code.
