MATLAB: Can I not get the modaldlg function to work? eg. user_response = modaldlg(‘​Title’,’Co​nfirm Close’);

Question

I am learnig Matlab and trying to use the modaldlg function call for a GUI and I receive the following error:

Undefined function 'modaldlg' for input arguments of type 'char'.

I have used the exact same code found in the 'Creating Graphical User Interfaces' pdf with no avail.

Nor does help even recognize this function call.

I am using Matlab2014b

Try one of the following, depending on the type of dialog you want:

user_response = errordlg('Error','Confirm Close', 'modal');
user_response = warndlg('Warning','Confirm Close', 'modal');
