I ran the code and expected to see all the modified b(i)'s as a result using the pause in the loop. But there was still a problem with the wrong number of parameters. Going back to some of my previous monkeying around with some of your examples, I recalled there being a function called factor(). Renaming factor to faktor the problem about the wrong number of parameters went away!  So this example has at least two problems!  This being the second one, and the  first is the wrong code inside the 3rd loop evaluating A(i,j).</span>
