using fprintf within a function

The function goes like this. How do I enter an fprintf statement so that the output looks like this:

>>num2let(83)

>>The corresponding letter grade to 83 is:B

function [grade]= num2let(n)

If n>89.49

grade='A'

elseif n<=89.49 & n=>79.5

grade='B'

......

...

elseif n<59.5 grade='F'

end

end

You have defined this as a function that returns a value. What do you want returned? The verbose string? Just the letter grade?

Remember, functions that return values cause the returned value to be printed out in the form

ans =

unless something is done with the returned value, or the display is suppressed by putting a semi-colon after the expression.

hi Caleb,

You can define your function without output like this :

 function []= num2let(n)

 if n > 89.49

 fprintf('>>The corresponding letter grade to %d is:A\n',n)

 elseif n<=89.49 && n>=79.5

 fprintf('>>The corresponding letter grade to %d is:B\n',n)

 % YOU COMPLETE YOUR FUNCTION WITH OTHER TESTS

 elseif n<59.5 

 %    grade='F'
    fprintf('>>The corresponding letter grade to %d is:F\n',n)

 end

 end

thank you.

When you have checked for n > 89.49 already, you do not need to check for elseif n <= 89.49 afterwards.

If you do not insist on fprintf, you can get the output using

grade = 83;
disp(['The corresponding letter grade to ' int2str(grade) ' is ' ...
      num2let(grade)])
