MATLAB学习的一些心得以及资料 仅限于私人交流学习(some MATLAB learning experience and information)

说明：  四旋翼无人机控制，matlab，simulink仿真分析，参考(Four-rotor UAV control, simulation analysis reference)

数学建模算法大全，内有很多代码，并有具体的教程（如何构建）(Mathematical modeling algorithm Daquan, there are a lot of code, and a specific tutorial (how to build))

对一个线性二阶系统进行基于阶跃响应模型的预测控制以及详细讲解(Predictive control based on step response model for a linear second-order system)

一个提取图象的elbp特征的程序，非常实用，效果也不错(A feature extraction procedure elbp image, very practical, with good results)

this code derivats image and get derivated image to you

说明：  （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 ((1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.)

matlab 中基于互相关函数的程序，希望对各位学者有帮助！(matlab cross correlation function based on the procedure, in the hope that scholars will help you!)

利用matlab采用最小二乘法很好的实现了振动阻尼的数值求解(Least square method using matlab realize very good vibration damping of the numerical solution)
