im trying to display grade scores and their letter grade.

im trying to display the letter grades from vector with disp() along with thier letter grades according to a grading scheme like this.-

grades = strings(size(S));

for i = 1;length(s)

if S(i) > Av + 1.3*Sd

grades(i) = "A";

elseif S(i) > Av + 0.5*Sd

grades(i) = "B";

elseif S(i) > Av - 0.5*Sd

grades(i) = "C";

elseif S(i) > Av - 1.3*Sd

grades(i) = "D";

else

grades(i) = "F";

end

end

and it shows all the grades and displays correctly but only shows the first letter grade and not the other 22. does anyone know how to fix this?

for i = 1:length(s)

The for loop is incorrect in your code. Change it as above by using : in place of ; By using ; the index i is set to 1 and not incremented to all values.
