MATLAB: Using switch-case. Return to beginning of switch-case statement

caseswitch

Essentially, I'd like the user to input a number 0-3.
i.e.
A = input ('Enter a number (0-3)');
switch A case 0 %Do something case 1 %Do something else case 2 %Do something else case 3 %Do something else otherwise %Invalid number.
end
So, in the otherwise statement, how would I go about returning to the beginning of the switch? So that one would not have to run the program again?

Best Answer

You don't even need otherwise ..
 isOk = false ;
 while ~isOk
    A = input ('Enter a number (0-3)');
    switch A
       case 0
          isOk = true ;
          % do something..


       case 1
          isOk = true ;
          % do something..
       case 2
          isOk = true ;
          % do something..
    end
 end
