使用matlab解决插值问题，包括 Lagrange 插值，分段线性插值，三次样条插值-Using matlab to solve the interpolation problem, including though laser interpolation, piecewise linear interpolation, cubic spline interpolation

关于数字图像的三次卷积插值，比三次样条，线性插值等更加有效-Cubic convolution interpolationfor digital image processing，it can be shown that the order of accuracy of the cubic convolution method is between that of linear interpolation and thaotf cubic splines.
