Feature Extraction from EEG

说明：  控制系统中PID分数阶控制系统MATLAB工具箱(MATLAB Toolbox for PID Fractional Order Control System)

利用matlab对图像进行灰度调整、拉伸处理和边缘检测(Use matlab image grayscale adjustment, stretch processing and edge detection)

matlab鼠标在画板移动自由画图，画的线不会断续(Matlab mouse drawing in the drawing board move freely, painting line will not be interrupted.)

最佳阵容问题 约束条件非常复杂 优化问题 暴力搜索(a matlab example)

连续阻尼物体运动的频谱，并画出了频谱曲线(Continuous spectrum damping the movement of objects, and plot the spectrum curve)

语音处理技术中用倒谱分析来求基音周期，为后续处理打下基础(Cepstral voice processing technology used to find pitch period analysis, laying a foundation for the subsequent treatment)

Simulink MIMO-OFDM in matlab

基于模糊规则的pso算法，用MATLAB编写的,绝对可用(Pso algorithm based on fuzzy rules, written using MATLAB, absolutely free)
