I know this is an invalid expression on line 9. How can I correct this error? Also, what error is this exactly? Matlab displayed multiple possibilities when trying to correct it.

clc
clear
x=input('Please enter a number:');
switch x
    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

Replace

case (3 5 7)

by

case {3,5,7}    

With curly brackets

"what error is this" It's break the switch-case-otherwise syntax
