Multiple cause exception handling

Consider this script,

try
  % code
catch e
  fprintf(1,'Exception identifier: %s\n',e.identifier);
  fprintf(1,'Exception message: %s\n',e.message);
end

When using try & catch to handle exceptions, if exception has multiple causes, it throws something like this:

Exception occurred!
Exception identifier: MATLAB:MException:MultipleErrors
Exception message: Error due to multiple causes.

Any way to parse the exceptions out one-by-one?

Does this help:

R = getReport(e);

? Otherwise check the list in e.cause and display it in a loop.

    ...
  catch ME
    if length(ME.cause) > 1
      for k = 1:length(ME.cause)
        fprintf('Exception message: %s\n', ME.cause{k}.message);
      end
    else
      fprintf('Exception message: %s\n', ME.message);
    end
  end

UNTESTED CODE I cannot run it currently. Maybe you have to adjust it, but I hope the idea got clear.

Thanks, getReport(e) works.
