WebFirst, understand that a real function can be analytic on an interval, but not on the entire real line. So what I try to do is consider f as a function of a complex variable in the neighborhood of the point say x = a in question. If f (z) (z complex) = f (x) when y = 0 (z = x + iy) then f (z) is an extension of f to a neighborhood of a. WebAnalytic functions compute an aggregate value based on a group of rows.
