Exception Handling

Capture data on errors

Any MATLAB^®  code that detects an error and throws an exception constructs an MException object. MATLAB can throw either predefined exceptions or exceptions that you construct.

Functions

`try, catch`	Execute statements and catch resulting errors
`MException`	Capture error information
`addCause`	Record additional causes of exception
`addCorrection`	Provide suggested fix for exception
`getReport`	Get error message for exception
`MException.last`	Return last uncaught exception
`rethrow`	Rethrow previously caught exception
`throw`	Throw exception
`throwAsCaller`	Throw exception as if occurs within calling function
`matlab.lang.correction.AppendArgumentsCorrection`	Correct error by appending missing input arguments
`matlab.lang.correction.ConvertToFunctionNotationCorrection`	Correct error by converting to function notation
`matlab.lang.correction.ReplaceIdentifierCorrection`	Correct error by replacing identifier in function call

Exception Handling in a MATLAB Application

It is a good programming practice to include error checking in your programs to ensure reliable operation under all conditions. You can decide how your programs respond to different types of errors.
- Throw an Exception
- Respond to an Exception
