Webis used for interpolation or extrapolation using splines. Splines are cubic polynomial functions that adapt by pieces to the points where you have to interpolate, in such a way that between pairs of contiguous points there are different polynomials (with exceptions). The derivative slope and second WebInterpolation You can also use the SPLINE function to interpolate between two of the values in Rx. E.g. to interpolate the y value corresponding to x = 8 (between x = 5 and x = 13), we use the formula =SPLINE (8,B4:B7,C4:C7) to obtain the value 2.243767 (as shown in cell L10 in Figure 3 of Spline Fitting ).

Web2D Interpolation in Excel Syntax =INTERPXY (x, y, q, [options]) Collapse all Description INTERPXY is a versatile 2D interpolation function based on splines. Use INTERPXY to interpolate from a set of (x,y) data points at an arbitrary point. Use INTERPXY to map a scattered (x,y) data points onto a uniform grid for easy plotting in Excel.
