POLYNOMIAL INTERPOLATION USING MATRIX METHOD IN MATLAB

Abstract

Data fitting is the problem of constructing such a continuous function. Many times, data given only at discrete points. The process of finding such a polynomial is called interpolation. In this study, researcher determining the polynomial interpolation by using matrix method. The manual calculation using matrix method take a long time and complicated especially for a points more than three. So, a mathematical modelling was built by using MATLAB programming to determine the polynomial interpolation for a given points using Matrix method. The result of the study presented that the manual calculating and the MATLAB mathematical modelling gave the same answer for the points given. This project will help students to understand further more about polynomial interpolation using matrix method as it is not only shows the equation for the polynomial but it also shows the graph for given points.
