MATLAB-phase-shifting-grating

说明：  一个MATLAB计算器程序,图形界面的 ,不过有个小BUG希望大家能(a calculator program, a graphical interface, but there is a small BUG hope we can s)

系统分析课程设计。倒立摆的空间状态控制。自己设置参数，(Systems Analysis Course Design. Inverted pendulum control space state. Set up their own parameters,)

说明：  用MATLAB写的神经网络PID控制源程序，类似刘金锟的《先进PID控制及MATLAB仿真》(MATLAB write neural network PID control source, Liu Kun similar to the "advanced PID control and MATLAB simulation")

matlab的gcv函数，可以用于求取正则化参数。是regtools工具箱中的(The gcv matlab function that can be used to strike the regularization parameter. Is regtools Toolbox)

matlab中cputime函数与进度条联合使用示例(matlab in cputime function used in conjunction with the progress bar example)

七电平逆变器的Simulink模型，调制方式采用SPWM方式，拓扑为H桥级联。(The Simulink model of Seven-level inverters adopts SPWM modulation mode and H-bridge cascade topology.)

基于MATLAB编写的前推回代法求解IEEE33节点电压(Forward and backward substitution method to solve the node voltage IEEE33)

主成分分析的c++实现使用奇异值分解svd算法(Principal Component Analysis based on svd algorithm ，used c++)

说明：  采用DRUDE模型，对多种金属（或者纯水）的介电常数进行数值计算。(By DRUDE model, a variety of metal (or water) in the numerical calculation of the dielectric constant.)

随机森林 MATLAB版算法，可以运行，能较好的实现分类算法，只是速度有点慢(Random forest MATLAB version of the algorithm can be run, better classification algorithms, but the speed is a little slow)
