I'm looking to ask the user to input a simple yes/no response, and then evaluate the response using a switch statement. This is essentially my code:

userInput = input('This is a prompt [y/n]');
input = lower(input);
switch userInput
    case 'y'
        %statements
    case 'n'
        %statements
end

However, when I type in y or n and hit enter, the code doesn't drop in to the appropriate cases (I set some breakpoints to make sure). I'm guessing there's a mismatch between the data type the switch statement is looking for and the data type I'm actually inputting to the console, but I'm not sure how to resolve this.
