Genetic algorithm feature selection by using Logistic Regression

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

说明：  粒子滤波的matlab源代码。在处理非高斯问题时比卡尔曼滤波强。经过测试可用。拿出来和大家分享，希望对大家有用。(Particle filter matlab source code. In dealing with the issue of non-Gaussian strong than Kalman filter. After the test can be used. Out to share with you all and hope for all of us useful.)

说明：  讲述了Matlab中小波降噪技术的使用，并讲述小波分解原理及如何检验。(Tells Matlab to use the wavelet noise reduction technology, and wavelet theory, and how about the test.)

异步电机矢量控制的原理图，用matlab建立了一部电机的模型，对矢量控制进行了仿真。(Schematics, vector control of induction motor using matlab model of a motor, vector control simulation.)

这是学习MATLAB很好的学习资料，是《MATLAB及在电子信息课程中的应用》一书的各章配套程序，很有帮助价值。(This is a very good learning materials to learn MATLAB is " MATLAB and in the course of electronic information" supporting the various chapters of the book program, useful values.)

matlab 的三象逆变仿真源代码，比较实用，谢谢(matlab simulation of the three inverter as source code, more practical, thanks)
