S curve of PLL System

捷联惯导仿真程序，可以比较好的帮助理解捷联惯导的原理，主要参考陈哲老师的捷联惯导原理(Strapdown inertial navigation simulation program, can help to understand better the principle of strapdown inertial navigation, strapdown references Chen Zhe teacher inertial navigation principle)

Very nice and compact HP filter function for matlab.

s变换，是当前比较流行的时频分析算法，可以用于地震数据时频分析和频谱分析，该程序基于matlab平台，实现了s变换和反变换。(s transformation, is the more popular time-frequency analysis algorithms, can be used for seismic data analysis and time-frequency spectrum analysis, the program based on matlab platform realize the s transform and inverse transform.)

粒子群算法，用于函数优化问题，也可以求得最短路等问题。(Particle Swarm Optimization)

这个是面部表情自动识别的源代码。它是基于Viola和Jones的面部检测算法和Gabor面部特征点的提取，然后使用训练过的神经网络来识别人脸表情。(This is the automatic recognition of facial expression source code. It is Viola and Jones face detection algorithms and Gabor facial feature point extraction, and then use the trained neural network based on facial expression recognition.)

滑模变结构控制在对一级倒立摆的控制，用于基础的变结构控制或者倒立摆控制学习。(Sliding Mode Variable Structure Control on an inverted pendulum control based on variable structure control for inverted pendulum control, or to learn.)

说明：  无约束一维极值问题中的黄金分割法，例程可调(Unconstrained extremal problem in the one-dimensional golden section method, routine adjustable)

Fractional discrete Fourier transforms
