matlab程序 主成分变换代码 以及测试数据(Principal component transformation matlab program code, and test data)

matlab要求编写函数，并画出图的matlab习题，供大家参考(prepared Matlab functions, and draws a plan of Matlab Exercise, for your reference! !)

simulink初学者教程，挺不错的，精通simulink系统仿真与控制(simulink tutorial for beginners, listening to good)

基于2阶消失矩的Daubechies尺度函数的TE波2维MRTD仿真，吸收边界条件为FDTD/PML连接边界。(2D MRTD TE mode baseed on 2nd-vanishing moments of Daubechies scaling function simulation, the absorbing boundary condition is FDTD/PML connection boundary.)

OMP算法的本质思想是：以贪婪迭代的方法选择D的列，使得在每次迭代的过程中所选择的列与当前冗余向量最大程度的相关，从原始信号向量中减去相关部分并反复迭代，只到迭代次数达到稀疏度K，停止迭代。(OMP compressed sensing )

说明：  在MATLAB中可以当做发射信号的缓冲，以提高系统的稳定性，从而防止数据的剧烈变化(BUFFER Buffer a signal vector into a matrix of data frames. Y = BUFFER(X,N) partitions signal vector X into nonoverlapping data segments (frames) of length N. Each data frame occupies one column in the output matrix, resulting in a matrix with N rows.)

掺铒光纤激光器动态模型数值化，采用掺铒光纤分段处理的方法，仿真光信号在环形腔内的传输(Erbium-doped fiber lasers numerical dynamic model using erbium-doped fiber section processing method, the simulation of the optical signal transmitted in the annular cavity)

说明：  搭建了模电电路，实现仿真并得到仿真U I波形(The analog circuit is built, and the simulation UI waveform is obtained)

对于非线性系统 如duffing和Lorenz系统，使用龙格库塔法求其系统响应，并画出相图和分岔图( For nonlinear systems such as duffing and Lorenz system, seeking its response system using Runge-Kutta method, and draw the phase diagram and bifurcation diagrams)
