I want to fit an exponential function in column C (using the Exp1p2 function), using blocks of 5 rows of data. There's lots here I don't know how to do, so I'll explain what I'm aiming for: Starting at row 5, I want to fit moving exponential functions (Exp1p2) like this: Cn = expfit (A(n-2):B(n+2)) so: C3 = expfit (A1:B5) C4 = expfit (A2:B6) C5 = expfit (A3:B7) etc Where C3 is row 3 of column C etc, and 'expfit' is however you would use the Exp1p2 function as a cell formula. Any help would be very much appreciated! [/quote]   Check here to include your profile signature. Check here to subscribe to this topic.
