Hi all!!

I have the script:

for h=1:2004
  for j=1:numberOfLines;  (problem)
      K(j,h)=T(j,h)/N(j,1);
  end
end

I don't know the number of lines and i need to put in the loop. What can i do?

Thank you!

If numberOfLines is supposed to be the numbers of rows in K, T, and N, then have a look at the size function:

numberOfLines = size(T, 1);

However, don't use loops for this sort of calculations. It's simply:

K = bsxfun(@rdivide, T, N);
