I have the following data sets, which shows the value of y for corresponding values of x
y x0 11 32 43 8
I want to fit a 2nd or 3rd order polynomial eg. y = a + bx + cx^2 + dx^3, where a, b, c, and d are coefficients that needs to be calculated. how can I calculate them using newton divided difference?
The advantage of Newton method is that it does not require recalcuating everything if a new data point is added to the set.
