This helps for writing Particle swarm optimization code

Dilution of precision part 2

说明：  画出系统的阶跃响应曲线，计算系统的上升时间，调节时间，超调量，稳态误差。。。(drawing the system s step response and comput its adjusting time \stastical error)

说明：  有限元方法编程matlab程序源代码，很好的(Finite element method matlab programming source code, well)

简单遗传算法MATLAB实现，详细的介绍了简单遗传算法的实现过程，并以一个简单的函数优化作为案例说明了其应用。但是由于该测试函数过于简单，在实际的应用过程中，还需要对相关参数进行调整，使其效率得到更大的提高。(Simple genetic algorithm based on MATLAB realize, describes in detail the process of simple genetic algorithm, and a simple function optimization as a case illustrate its application. However, since the test function is too simple, in the actual application process, the relevant parameters need to be adjusted to greater increase efficiency.)

svm demo的实现 实现SVM训练测试的全过程，对于初学者很实用，也能彻底了解SVM运行过程，知其然知其所以然，国外一权威网站上下载的，上传以供分享学习(svm demo of SVM training tests to achieve the realization of the entire process, a foreign authority Web site to download and upload for sharing learning)

加速度时程曲线通过matlab经过频域积分变换为位移时程曲线(Acceleration time history curve matlab integral transformation of the frequency domain through the process curve displacement)

说明：  电机控制回路的simulink模拟。使用二阶速度反馈控制，并使用电流保护。(Motor control loop simulation simulink. The use of second-order velocity feedback control and the use of current protection.)

适用于大部分类型的陀螺数据处理的matalb程序,包括标度因数,零偏,补偿等信息(Applicable to most types of gyro data processing matalb procedures, including scale factor, bias, compensation and other information)
