详细介绍matlab的许多有用的功能和一些重要功能的语法，并加一些经典试验(Matlab detail the many useful features and some important features of the grammar, and add some classical test)

利用基于粒子群算法的灰色模型对航空发电机进行状态趋势分析技术研究，所得到的分析结果平均相对误差为3.99 。此模型为粒子群优化算法对GM(1,1)模型的改进模型，因此称为基于粒子群优化算法的GM(1,1)模型。(Using aviation turbine gray model based on particle swarm optimization state trend analysis technology research, analysis the average relative error is 3.99 . This model for particle swarm optimization algorithm improved model GM (1,1) model, the so called GM (1,1) model based on particle swarm optimization algorithm.)

需将图形文件复制到D盘根目录，或修改程序中的相关文件的路径。 计算机运行可能会出现这样的警告：Warning: Function call WAVEDEC2 invokes inexact match F:Matlab oolboxwaveletwaveletwavedec2.m. > In Wnn0802 at 18 无妨，没关系的，不影响运算结果。(Need to copy files to the D graphics root directory, or modify the program in the path of the relevant documents. Computer running such a warning might appear: Warning: Function call WAVEDEC2 invokes inexact match F: Matlab toolbox wavelet wavelet wavedec2.m> In Wnn0802 at 18 anyway, it does not matter, does not affect the result of the operation.)

Induction machine stator fault

可以对比较复杂的微分方程进行求解，比如说是二阶系数微分方程。(More complex differential equations can be solved, for example, is a second-order differential equation coefficients.)

随机子空间算法，可代入数据进行模态参数识别(Subspace algorithm, modal parameter identification)

用MATLAB编写的遗传算法路径规划，窗函数法设计一个数字带通FIR滤波器，一种噪声辅助数据分析方法。( Genetic algorithms using MATLAB path planning, A window function design FIR digital band-pass filter, A noise auxiliary data analysis method.)

这是我自己写的对图像进行预处理的matlab源程序，主要是对图像进行光照补偿、旋转与尺度归一化。上传上来和大家一起学习、分享。(This is I wrote it myself pretreatment image matlab source, mainly for image illumination compensation, rotation and scale normalized. From up and study together, to share.)

国外、国内的最多的fastica程序，很好用，参数不用改，直接用默认的即可。(fastica)

说明：  利用小波变换实现对故障信号的特征提取 构造特征向量(Wavelet transform feature extraction of fault signals structural feature vector)
