这是一个MATLAB 仿真程序，用于仿真光栅衍射。(Diffraction gratings used for the simulation.)

灰色关联分析的matlab代码，可实现矩阵自动生生关联度(Grey Relational Analysis)

卡尔曼滤波算法是一种状态估计算法，它是最小二乘法的特殊形式，所以，卡尔曼滤波算法也能做系统辨识，这个代码是自己写的，基于卡尔曼滤波算法的系统辨识，希望对大家有用(Kalman filter algorithm is a state estimation algorithm, which is a special form of least squares method, so the Kalman filter algorithm can do system identification, this code is to write their own, based on Kalman filtering system identification algorithm, we want to useful)

基于状态空间模型的预测控制程序，参考了钱积新的《预测控制》(Predictive control program based on state space model, refer to the Qian Jixin’ s predictive control )

FFT快速傅立叶变换的代码，只需要Matlab环境即可运行。需要输入分析数据。(FFT Fast Fourier Transform code, only need to run Matlab environment. Need to enter data.)

仿真实现了伪随机码的产生过程,包括m序列，C/A码以及金码等(simulation of pseudo-random code)

用matlab实现多幅图片的downsample 把图片变成低分辨率的小图片。(Using matlab implementation of the downsample pictures put into a low-resolution picture of the small picture.)

利用FFT实现基于MP的信号稀疏分解程序(Using FFT-based signal sparse decomposition process MP)

说明：  马氏距离的仿射不变性删除误匹配特征点 对，据此可求取2幅源图像间的仿射变换参数(Mahalanobis distance of the affine invariant features remove the false matching points Yes, according to the source to obtain two parameter affine transformation between images)

matlab自学经典教程，对初学者入门帮助较大(matlab self-classic guide more helpful to the beginner)
