Question

Hello. I am trying to make a program that allows me to input different strings and displays the correct statement based on the string.

This is my code

Planet= input('Planet:');
switch lower(Planet)
    case {'mercury','venus','earth','mars'}
        disp('This is a Inner Planet')
    case {'jupiter','saturn','uranus','neptune'}
        disp('This is a Outer Planet')
    otherwise 
        disp('No such planet exists.')
end

And the error i get is

    >> switchcase
    Planet:Earth
    Error using input
    Undefined function or variable 'Earth'.
    Error in switchcase (line 1)
    Planet= input('Planet:');
