msgText = getReport(exception,type,'hyperlinks',hlink)
DescriptionmsgText = getReport(exception)
gets the error message for an exception and returns it as formatted text, msgText. The message is the value of the message property of the MException object, exception. It is the same text that MATLAB® displays when it throws the exception.msgText = getReport(exception,type)
returns the error message using the indicated level of detail, specified by type. msgText = getReport(exception,type,'hyperlinks',hlink)
uses the value of hlink to determine whether to include active hyperlinks to the failing lines of code within the error message.Input Argumentsexpand allexception -- Exception object that provides error messageMException object Exception object that provides the error message, specified as a scalar MException object. type -- Detail indicator of message'extended' (default) | 'basic' Detail indicator of the message returned, specified as 'extended' or 'basic'. type ValuemsgText Detail
returns control to the keyboard. The error message contains the input string message. The error command has no effect if message is a null string. error('message',a1,a2,...) displays a message string that contains formatting conversion characters, such as those used with the MATLAB sprintf function. Each conversion character in message is converted to one of the values a1, a2, ... in the argument list. Note MATLAB converts special characters (like \n and %d) in the error message string only when you specify more than one input argument with error. See Example 3 below. error('message_id','message') attaches a unique message identifier, or message_id, to the error message. The identifier enables you to better identify the source of an error. See Message Identifiers and Using Message Identifiers with lasterr in the MATLAB documentation for more information on the message_id argument and how to use it. error('message_id','message',a1,a2, ...) includes formatting conversion characters in message, and the character translations a1, a2, ... Examples Example 1 The error function provides an error return from M-files: function foo(x,y) if nargin ~= 2 error('Wrong number of input arguments') end The returned error message looks like this: foo(pi) ??? Error using ==> foo Wrong number of input arguments Example 2 Specify a message identifier and error message string with error: error('MyToolbox:angleTooLarge', ... 'The angle specified must be less than 90 degrees.'); In your error handling code, use lasterr to determine the message identifier and error message string for the failing operation: [errmsg, msgid] = lasterr errmsg = The angle specified must be less than 90 degrees. msgid = MyToolbox:angleTooLarge Example 3 MATLAB converts special characters (like \n and %d) in the error message string only when you specify more than one input argument with error. In the single argument case shown below, \n is taken to mean backslash-n. It is not converted to a newline character: error('In this case, the newline \n is not converted.') ??? In this case, the newline \n is not converted. But, when more than one argument is specified, MATLAB does convert special characters. This holds true regardless of whether the additional argument supplies conversion values or is a message ide
