I keep getting the error "Error using input The first argument to INPUT must be a character vector." What does this mean? I've tried searching for it, yet cannot figure it out.

clc
clear
hello = input("Please enter a number");
switch hello
    case 0
        disp("You have entered 0");
    case 2
        disp("Your number is even and prime.");
    case (3, 5, 7)
        disp("Your number is prime");
    otherwise
        disp("Invalid number");
end

Change the " to '

In your release input() had not yet been extended to handle string objects .
