WebView history. In numerical analysis, polynomial interpolation is the interpolation of a given data set by the polynomial of lowest possible degree that passes through the points of the dataset. [1] Given a set of n + 1 data points , with no two the same, a polynomial function is said to interpolate the data if for each . WebIn other words, interpolate the column E values corresponding to the column F values. For example, A3=3 and B3=7. In this case, F7=7 and E7=3 because B already included the integer 7 and has a matching value in column A. However, F8=8, which is an intermediate value not contained in column B. So E8 will lie between 3 and 4, based on the ...
