The Realization of Spline Interpolation Based on MATLAB

Interpolation method is the most common engineering practice function approximation method,which uses a finite number of data points to achieve the fitting of the function.This paper introduced the concept of interpolation,then described the concept and conditions of spline interpolation.The most common spline interpolation methods,cubic spline interpolation and B-spline interpolation,were discussed mainly by means of mathematical analysis and simulation based on MATLAB toolbox.
