MATLAB program to find circular convolution using linear convolution

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.

插值与拟合的matlab实现，雅克比迭代求解线性方程组课设,意信号卷积的运算,并且绘制图象。- Interpolation and fitting matlab implementation, Jacobi iteration for solving linear equations class-based, Convolution operation is intended to signal and image rendering.
