This code interpolate, differentiate(up to any order) and evaluate for a given data sets at a specific point. As this code uses Newton's Forward/Backward and Sterling method, therefore the interval of the independent variable must be equal.
At first it generates a function using the data sets and then evaluate or differentiate it as required.
