      • SRS1 Cubic Spline for Excel adds several spline and linear interpolation functions to Microsoft Excel. The cubic spline function smoothly interpolates between given data points. Bessel and OneWay (monotonic) spline functions provide a more constrained smooth fit to data. A linear interpolation function is also included.
      • Linear interpolation, in computer graphics often called "LERP" (Linear interpolation), is a very simple (if not THE simplest) method of interpolation. For a set of discrete values linear interpolation can approximate other values inbetween, assuming a linear developement between these discrete values.
      • The advantage of this method is that it is a single function which makes it easy to interpolate a grid of values as shown in this image (note the cells are coloured according to the values to better visualise the effect of the interpolation):
    • In the "Points at which Interpolant Sought" section, enter the x-values at which the interpolating y-values are to be calculated.

      • vlookup_int has the same inputs as VLOOKUP and works in the same way, except that it will interpolate between values if required. I also added a feature that brings in the table of values as an array and then sorts it in ascending order (without affecting the values in the worksheet), which means you don’t have to worry about sorting your data before hand.

    you can download the function from Excel4engineers.tInterpolation Example in ExcelWWW.excel4engineers.com Cubic Spline Interpolation. We start from a table of points for for the function . That makes points and intervals between them. The cubic spline interpolation is a piecewise continuous curve, passing through each of the values in the table. There is a separate cubic polynomial for each interval, each with its own coefficients:

    subroutine interp1 ( xData, yData, xVal, yVal ) ! Inputs: xData = a vector of the x-values of the data to be interpolated ! yData = a vector of the y-values of the data to be interpolated ! xVal = a vector of the x-values where interpolation should be performed ! Interpolation between two precision-recall points is non-linear. The ratio of positives and negatives defines the baseline. A ROC point and a precision-recall point always have a one-to-one relationship. These characters are also important when the plot is applied to imbalanced datasets. 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. With optional arguments, you can control the interpolating spline properties.
