Polynomial interpolation involves finding a polynomial of order . n. that passes through the . n +1 points. One of the methods of interpolation is called the method. direct Other methods include Newton’s divided difference polynomial and the Lagrangian method interpolation method. We will discuss the direct method in this chapter.

Direct Method The direct method of interpolation is based on the following premise. Given data points, fit a polynomial of order as given below (1) through the data, where are real constants. Since values of are given at values of , one can write equations. Then the constants, can be found by solving the simultaneous linear equations.

Example To maximize a catch of bass in a lake, it is suggested to throw the line to the depth of thermocline. The characteristic feature of this area is the sudden change in temperature. We are given the temperature vs. depth plot for a lake. Determine the value of the temperature at z = − 7. 5 using the direct method for cubic interpolation.

The simplest method is the direct method that construct the polynomial interpolation by solving the system of linear equations created from the given set of ...
