MATLAB: Elseif to switch statement

elseif

I am attempting to switch this into a switch statement.
TestScore = input('Enter a score from the keyboard  ')
if(TestScore > 89)
    disp('Your Letter grade is  A')
elseif(TestScore > 79)
    disp('Your Letter grade is  B')
elseif(TestScore > 69)
    disp('Your Letter grade is  C')
elseif(TestScore > 59)
    disp('Your Letter grade is  D')
else
    disp('Your Letter grade is  F')
end

There's nothing wrong with the if/elseif/else syntax but the conditional statements could be tightened up.
If you prefer a switch-case, 
switch true
    case (TestScore > 89 && TestScore <=100)
        disp('Your Letter grade is  A')
    case (TestScore > 79 && TestScore <= 89)
        disp('Your Letter grade is  B')
    case (TestScore > 69 && TestScore <= 79)
        disp('Your Letter grade is  C')
    case (TestScore > 59 && TestScore <= 69)
        disp('Your Letter grade is  D')
    case (TestScore >=0 && TestScore <= 59)
        disp('Your Letter grade is  F')
    otherwise
        disp('TestScore did not match grade ranges.')
end
