Translate Capture Information About ExceptionsOverviewWhen the MATLAB® software throws an exception, it captures information about what caused the error in a data structure called an MException object. This object is an instance of the MATLAB MException class. You can obtain access to the MException object by catching the exception before your program aborts and accessing the object constructed for this particular error via the catch command. W

If no error occurs within try block, MATLAB skips the entire catch block.For example, a try/catch statement can prevent the need to throw errors. Consider the combinations function that returns the number of combinations of k elements from n elements:function com = combinations(n,k) com = factorial(n)/(factorial(k)*factorial(n-k)); endMATLAB throws an error whenever k > n. You cannot construct a set with more elements, k, than elements you possess, n. Using a try/catch statement, you can avoid the error and execute this function regardless of the order of inputs:function com = robust_combine(n,k) try com = factorial(n)/(factorial(k)*factorial(n-k)); catch com = factorial(k)/(factorial(n)*factorial(k-n)); end endrobust_com

I am handling possible error in the following way try matStart(MatObj); catch err msgbox('Error in Processing Figures!','Error!','error','modal'); fprintf(2,err.message); sprintf('\n'); display(err.message); end as you can probably guess, this prints the error that caused the exception.But this only prints the very first function that caused the error. I want the whole error stack to be shown down to the last nested function that caused the error to occur. Can tis be done? matlab error-handling share|improve this question asked Aug 14 '12 at 0:30 Adnan 195421 add a comment| 2 Answers 2 active oldest votes up vote 15 down vote accepted Yes, the function you're looking for is "getReport". You'll want the 'extended' report. Using getReport, your code would look like this try matStart(MatObj); catch err msgbox('Error in Processing Figures!','Error!','error','modal'); disp(getReport(err,'extended')); end This will display the same information as an uncaught exception in matlab that prints the full stack trace, though of course the text won't be red. share|improve this answer answered Aug 14 '12 at 2:35 lawinslow 62158 add a comment| up vote 7 down vote Following on from
