This is my text:

function grade=switchletgrade1(quiz)

if quiz<0 ||quiz>4

grade='X'

else switch quiz

case 3

grade='B'

case 4

 grade='A'
        otherwise
            grade='C'
end

end

end

Answer 1

Your code works error-free for me.

Is it possible that you are inadvertently calling a different file with a pre-debugged version? Does the command

 >> which switchletgrade1

give the file location you expect?
