Abstract

There is necessity of a method/formula, for representing a given set of numerical data on a pair of variables by a the curve, in interpolation by the approach which consists of the representation of numerical data by a polynomial first and then to compute the value of the dependent variable from the polynomial corresponding to any given value of the independent variable. Due to this necessity, a method has been composed for representing a given set of numerical data on a pair of variables by a polynomial curve. The method has been composed with the help of elementary column transformation of matrix. This paper describes the method composed here with numerical example in order to show the application of the method to numerical data.

Keywords

Numerical data, polynomial curve, matrix inversion, Gauss Jordan method.
