Using fprintf in MATLAB With Function

Let's see this example for define a function in MATLAB : -

function []= fun2let(n)
 if n > 90.00
 fprintf('>>letter grade to %d is:A+\n',n)
 elseif n<=89.49 && n>=80.00
 fprintf('>>letter grade to %d is:B+\n',n)
 % YOU COMPLETE YOUR FUNCTION WITH OTHER TESTS
 elseif n<59.5 
 %    grade='Fail'
    fprintf('>> letter grade to %d is:Fail\n',n)
 end
 end
