说明：  matlab中微分方程的解法，及其应该注意的问题(matlab in the solution of differential equations, and should pay attention to the issue of)

半定规划内点法数据整理交直流系统统一无功优化算法，系数矩阵的确定。(Interior point method for semidefinite programming data collation AC and DC systems unified reactive power optimization algorithm to determine the coefficient matrix.)

给定数据的心电波形的频谱分析，刚刚接触matlab。(Given the spectrum of ECG data analysis, just contact matlab.)

MIMO-OFDM雷达波束形成及优化。首先，MIMO-OFDM雷达和OFDM-MIMO雷达的定义在不同的期刊是不同的。这里MIMO-OFDM雷达的定义同IET期刊，即发射阵列应用频率分集。MIMO-OFDM雷达同时使用了频率分集和波形分集，当发射阵列阵元间距是接收阵列阵元间距的N倍时，虚拟孔径最大，这时波束最窄，空域分辨力最高。(Beamforming and its optimization of MIMO-OFDM radar, the definition of MIMO-OFDM radar and OFDM-MIMO radar in different journal are fifferent. the MIMO-OFDM radar is equal to IET journal, that is transmitting end is frequency diverse array. Both frequency diversity and waveforms diversity are used in MIMO-OFDM radar, while interelement range in transmitting end is N times of receiving end, the virtual aperture is maximum, and spatial resolution is maximum.)

说明：  用于特征降维，特征融合，相关分析等多元数据分析的广义典型相关分析（GCCA）Matlab代码实现。(For feature reduction, feature fusion, correlation analysis, multivariate data analysis using generalized canonical correlation analysis (GCCA) Matlab code implementation.)

高通滤波器的MATLAB程序，简单实用易懂(High-pass filter MATLAB program, simple and practical and easy to understand)

基于simulink的四旋翼飞行器动力学建模与简单PID控制。(Based on the four-rotor dynamics modeling with a simple PID control simulink.)

蔡氏混沌电路的仿真,混沌同步中常用同步方法的仿真，基于蔡氏混沌电路(cai chaos control)
