说明：  遗传算法在优化路径中的应用研究，MATLAB程序。

说明：  matlab说明，各种各样的公式符号说明(matlab shows a variety of formulas symbol description)

一个关于TV模型算法的编写程序代码 具有很好的去除噪声效果(A about TV model algorithm of writing code has the very good for removing noise effect)

围绕粒子群的当前质心对粒子群重新初始化.这样，每个粒子在随后的迭代中将在新的位置带着粒子在上次搜索中获得的“运动惯性”（wvi）向Pi，Pg的方向前进，从而可以在粒子群的运动过程中获得新的位置，增加求得更优解的机会.随着迭代的继续，经过变异的粒子群又将趋向于同一点，当粒子群收敛到一定程度时又进行下一次变异，如此反复，直到迭代结束.(particle swarm around the center of mass of the current PSO reinitialization. Thus, Each particle in the next iteration will be in the new location with particles in the last search was the "inertia" (wvi ) Pi, Pg orientation, and thus can PSO course of the campaign was a new position, increase seek better solutions opportunities. With the continued iteration, after variation of PSO will tend to the same point. When PSO converge to a certain extent when the next variation, so repeatedly, until the end of iteration.)

音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)

说明：  实现数字图像滤波,能够较好的实现图像的滤波霸霸工傀要革故鼎新(to filter digital image)

最优控制率下的PID控制器参数，使其具有更好的鲁棒性和自适应的能力。(Optimal control rate of PID controller parameters, it has better robustness and adaptive capacity.)

使用Matlab实现特殊矩阵，对初学Matlab的人很有帮助(It has benefits for learners)
