使用PCA算法的故障诊断MATLAB仿真程序(PCA fault diagnosis procedure)

利用Matlab求二维离散系统的分岔图程序。 在非线性动力学及复杂经济学中经常用到类似的问题。也可以用来画其他更高维数的离散映射系统的分岔图。很实用。(using Matlab for discrete two-dimensional map of bifurcation process. In nonlinear dynamics and complex economics frequently used similar problems. Can also be used for other higher-dimensional painting of a few discrete mapping system bifurcation plan. Practical.)

基于改进的ARMA模型 定阶预测方法，经过调试，程序能顺利运行(Improved ARMA model order prediction method, after debugging, the program can run smoothly)

用矩阵的奇异值分解法确定ARMA模型的阶次，估计模型参数(ARMA model to determine the matrix of the singular value decomposition of the order, the estimated model parameters)

一个用matlab编写的最近邻插值法求图像的范大于缩小的小程序(Matlab prepared using a nearest neighbor interpolation for images larger than narrow the scope of small programs)

说明：  本程序实现了信号稀疏分解的经典算法OMP！(This program implements a classic signal sparse decomposition algorithm OMP!)

MVAcauchy plots three probability density functions (left) and three cumulative density functions (right) of the Cauchy distribution with m = 0 and different scale parameters (C1 stands for a Cauchy distribution with s = 1, etc).

在matlab中利用雷克子波应用褶积公式合成一维地震记录，同时对比零相位和最小相位雷克子波的效果(Synthesis of one-dimensional seismic records in matlab using the Ricker wavelet applications convolution formula)
