Finding average of iterated curves

I have a code that generates multiple curves from a set of data that gets random error added to it, so after each iteration of the full code, the output curve is different. How can I get an average of these curves?

It depends on how you save these curves. In a matrix?

Write a function "fullcode" that returns your curve, than you can use something like this

for i = 1:N
  result(i,:) = fullcode;
end

mean(result)
