Get the error message from the exception.

exception = MException.last;
msgText = getReport(exception)

In a file in your current working folder, create the following function in testFunc.m.

function a = testFunc
try
    a = notaFunction(5,6);
catch a

end

Since the function, notaFunction, does not exist, testFunc returns an MException object.

At the command prompt, call testFunc and get the error message.

m = testFunc;
msgText = getReport(m)

msgText =

Undefined function 'notaFunction' for input arguments of type 'double'.

Error in testFunc (line 3)
    a = notaFunction(5,6);

Specify that the error message only contains the error message and not the stack information.

msgText = getReport(m,'basic')

msgText =

Undefined function 'notaFunction' for input arguments of type 'double'.

Cause MATLAB to throw an exception.

try
