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

This is what I got, It seems to be different, but they both work. Do you know if this one is incorrect?
TestScore = input('Enter a score from the keyboard ');
switch TestScore
case num2cell(90:100)
disp('Your Letter grade is A')
case num2cell(80:89)
disp('Your Letter grade is B')
case num2cell(70:79)
disp('Your Letter grade is C')
case num2cell(60:69)
disp('Your Letter grade is D')
otherwise
disp('Your Letter grade is F')
end

Test the following grades:
  • 101 (accidentally entered by user)
  • 91.5
