I can easily do a linear interpolation between these points, but would like to find a way to interpolate between the points on the generated curve, as the linear interpolations …
Linear & Polynomial Interpolation in Excel - Microsoft Community
WebJun 27, 2012 · The equation of such a plane is f ( x, y) = a x + b y + c, that is to dertermine our plane we need to compute a, b and c. As we want f to interpolate the given values, we need f ( x i, y i) = D i, 1 ≤ i ≤ 3. We compute them as above (solving the linear system f ( x i, y i) = D i ). Then we just interpolate by evaluating f (as we did in 1D ... WebBut as long as the known-Y and known-X arrays have just two elements each, FORECAST interpolates the actual data points.
