Jacobi迭代法、Gauss-Seidel迭代法、超松弛迭代法（SOR方法）分别求解线性方程组的近似解(Jacobi iteration, Gauss-Seidel iteration, SOR (SOR method) for solving linear equations are approximate solutions)

说明：  zernike矩的Matlab实现，可以计算任意阶矩(Matlab implementation zernike moments, moments of any order can be calculated)

PSCAD下含光伏、风电的微网模型。很实用(And PSCAD under including photovoltaic, wind power, micro-network model)

说明：  两个关于数值分析的matlab代码，十分有用(2 matlab code on Numerical Analysis, very useful)

从网格划分软件Gambit读取3维网格的Matlab程序，来自《节点间断迦辽金方法》一书(Matlab program read from the meshing software Gambit three-dimensional grid, from the node discontinuous Galerkin method, " a book)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

Harris采用了一种新的角点判定方法。矩阵M的两个特征向量l1和l2与矩阵M的主曲率成正比。Harris利用l1, l2来表征变化最快和最慢的两个方向.若两个都很大就是角点,一个大一个小就是边缘,两个都小就是在变化缓慢的图像区域.(Harris adopted a new method of determining the corner. Matrix M of two feature vectors l1 and l2 with the matrix M is proportional to the principal curvatures. Harris use l1, l2 to characterize changes in the fastest and slowest in two directions. If both are great that corner, a little is a big edge, both small change is slow in the image area.)
