A simple FEM code in matlab

all matlab data for the implementation

各种系统辨识方法，对一阶，二阶，三阶自衡系统进行辨识。用到的方法有面积法等等……(Various system identification method, first, second, third from the value system identification. The methods used in an area of law, etc ... ...)

求解的长直接地金属槽和平板电容中的电场，并画出等位线分布图(Calculation of Electron Physics )

Collection of Sparse Representation Library(Berkeley+Gatech)

模式识别。PCA实例，经调试可用，希望能帮到需要的人。(Pattern Recognition. PCA instance, debugging is available, I hope to help people in need.)

固高直线倒立摆MATLAB版本控制程序，采用实时内核方式实现精确定时(Googol linear inverted pendulum MATLAB version control program, using real-time kernel mode to achieve precise timing)

Hdb3码及其功率谱密度法 (Partial least squares)

说明：  利用AMDF法求语音信号的基音周期（结果为时频图）(Pitch detection by AMDF algorithm)

说明：  跳频图案的产生模块，互相学习，参考一下挺有帮助的(Frequency hopping pattern generation module, mutual learning, reference winter ridge help)
