MATLAB经典教程—从入门到精通的pdf，很好的一本书(MATLAB classic guide- from entry to the proficient pdf good a book)

本代码用matlab编写Runge-Kutta算法程序，并且用ode45函数的编写代码进行对比分析。(The code is written using Runge-Kutta algorithm matlab program, and were analyzed by writing code ode45 function)

Affine spatial interest points detection using scale space analysis

用多尺度卡尔曼滤波法，对信号参数进行识别估计。高频信号和低频信号识别结合起来改进了算法识别的精确度和准确度。(It is an implementation of hierarchical (a.k.a. multi-scale) Kalman filter using belief propagation. The model parameters are estimated by expectation maximization (EM) algorithm. In this implementation, we considered two time series with different frequencies. The messages between high and low frequency signals are combined to improve the estimation and prediction.)

说明：  实现信号的功率谱估计，AR,MUSIC,FFT,周期图法(Achieve signal power spectrum estimation, AR, MUSIC, FFT, periodogram)

Z源逆变器的matlab仿真模型，仿真结果可以使用，但是存在一点小问题，欢迎我们交流(Z-source inverter matlab simulation model, the simulation results can be used, but there is a little problem, welcome to our exchange)

This submission contains 3 examples to illustrate the change in peak time, settling time and percent overshoot as the poles of a 2nd order system move horizontaly,

本例程是三电平故障诊断仿真，通过观察输出波形来判断哪个开关管有损坏，是什么损坏(This Simulation files is a three-level fault diagnosis simulation, by observing the output waveform to determine which switch is damaged, what damage is)

设计凸轮，对于偏心直动凸轮，可作出理论轮廓线和实际轮廓线(Design of the cam, the eccentric cam may be made to the theoretical contour and the actual contour)
