MATLABaPID

A linear system is such that produces its output as a linear combination of its current and previous inputs and its previous outputs [13]. It can be described as time-invariant if the system parameters do not change with time

本代码是基于镜头分割的关键帧提取代码，是用matlab来实现的。(The code is the code key frame extraction based on shot segmentation is achieved using matlab.)

阵列信号处理的高分辨率估计，相控阵天线的方向图（切比雪夫加权），包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角。( High-resolution array signal processing estimates, Phased array antenna pattern (Chebyshev weights), It comprises aircraft flight attitude control, such as slip angle, tilt angle, roll angle, pitch angle.)

解决TSP问题的TS算法MATLAB实现，其中加入了变异算法，当然也可以去掉这个步骤，调用TS_TSP(N, inStart, IsBianYi)，N是城市数目，inStart是起始城市的序号，IsBianYi就是选择变异否，如果为0则不要变异，否则就是结合变异算子的TS算法。 至于下面的参数可以自己调： T：总的循环次数； tabulength：禁忌长度； Pby：变异概率； (Solve the TSP problem MATLAB realize TS algorithm, which joined the variance algorithm, of course, this step can also be removed, call TS_TSP (N, inStart, IsBianYi), N is the number of cities, inStart is the serial number of the starting cities, IsBianYi is to choose variation has, if not for the variation of 0, otherwise, it is combined with mutation of the TS algorithm. As for the following parameters can be their own tune: T: total number of the cycle tabulength: taboo length Pby: mutation probability )
