MATLAB

The program is about buck converter PWM in simulink.

这是我多年MATLAB编程的技巧汇总，希望对大家有用。里面包含命名规则，怎样优化程序等等。(This is my years of MATLAB programming skills summary, I hope useful for everyone. Which contains the naming rules, how to optimize procedures.)

State Space Simulink Model with Two variables.

SOR法，数值计算中的方法，基于matlab的程序(SOR method, numerical calculation methods, procedures based on matlab)

彩色图像转灰度图像的三种算法，matlab实现(Color image to grayscale image of the three algorithms, matlab implementation)

蒙特卡洛实验，得出曲线为检测性能曲线，为取不同信噪比下的PD与SNR的关系。(The Monte Carlo experiment shows that the curve is the detection performance curve, and the relationship between PD and SNR at different SNR is obtained.)

基于Mathcad（也可转为matlab程序）的旋转系绳系统模型，以牛顿力学建模，考虑系绳弹性，可用于任意开普勒轨道建模仿真。(The Mathcad based model of the rotating tether system, which considers the tether elasticity, can be used for arbitrary Kepler orbit modeling and simulation.)

利用特别功能找出完美的符合。非常有用的程序。。(this is a very useful tool to find hht which is hilbert trans,)

说明：  BP神经网络的仿真，能够拟合各种函数，支持梯度下降法和LM两种训练算法。所有代码自己编写，没有使用matlab自带的函数，是学习的最佳范本。(The simulation of BP neural network can fit various functions and supports two training algorithms, gradient descent method and LM. All the code is written by myself, without using the functions that come with matlab, it is the best model for learning.)

说明：  应用无迹卡尔曼滤波较好的实现单目标跟踪。(Unscented Kalman filter applied to achieve good single-target tracking.)
