粒子群算法（PSO）优化BP神经网络，用来进行非线性的校正，效果良好(Particle swarm optimization (PSO) to optimize BP neural network, used for non-linear correction, to good effect)

该代码是Crystal地震模型的数值模拟，运行较慢(This codes is written for Seismic Crystal Simulations )

通过确定特征值所张成的特征空间上的主成分分析方法，确定对确定输出变量间的输入变量的相互影响关系。(By determining the characteristic features of the value of the Zhang space on principal component analysis to determine the output variables in determining the input variables in our cases.)

在Simulink平台上对永磁同步电机(PMSM)实现直接转矩控制的仿真模型，使用无传感器控制方法，是国外的成品模型。(On the platform in Simulink for permanent magnet synchronous motor (PMSM) direct torque control of realize simulation model, the use of sensorless control method, is abroad finished product model.)

positively invariant sets and their application to the analysis and synthesis of control systems.

说明：  微多普勒仿真，用于微多普勒仿真计算，方便快捷(Micro doppler simulation)

说明：  fault current limiter bu pscad

用模糊函数法进行时频分析，特别好的程序，本人写论文用到的。(Ambiguity function method using time-frequency analysis, in particular, a good program, I used to write papers.)

This file contains a lab which is developed to implement a low pass filter using windowing technique. We study the way how to design FIR digital filters and how Matlab offers tools for the design.

兔子繁殖问题，好累啊 重要的是画出曲线，而不是柱状图(Rabbit breeding problems, tired. what important is to draw the curve, rather than the histogram)
