Have a close look at your code. You set

raw{r+1,cols+2}=s;

before you determine the value of s in the following if s... clauses. Compare against s(r-1), s computed in your first while loop, and assign the corresponding grade to raw{r+1, cols+2}:

if s(r-1) >= 90
  raw{r+1, cols+2} = 'F'
else...% always use s(r-1)

end
r = r +1;

[Thorsten]

My fault: must be s(r).
