说明：  一个多输入多输出（mimo)系统的仿真matlab程序，希望对大家有所帮助(a multi-input multi-output (MIMO) systems Matlab simulation procedures, we hope to help)

matlab的函数大全，挺有用的，不错哦！(function about matlab，very useful！)

Crystal Clear SSI for Operational Modal Analysis

说明：  包含两个灰色预测模型的MATLAB代码实现。1.灰色预测GM（1，1）模型。2.改变初始条件，以1-AGO序列的最后一个数据为初始条件的灰色预测模型。(Contains two gray prediction model matlab code. 1. Grey Prediction GM (1,1) model. 2. Change the initial condition, take the last data of 1-AGO series as the initial condition of grey prediction model.)

这是一个MATLAB算例，在信号处理中的去噪可以用的到。新手合适。(This is a MATLAB example, in signal processing can be used to de-noising. Novice appropriate.)

以中等纯度的精馏塔为研究对象，考虑到不等分子溢流的影响和非理想的汽液平衡，可以得到塔顶产品轻组分含量Y与回流量L之间的传递函数为： 控制要求： 1.采用积分分离 PID控制算法将塔顶轻组分含量Y控制在0.99 2.采用继电法整定PID参数 3.整定效果验证：当被控过程参数时变时，如滞后时间由4→8，开环增益由3.4→6时, 讨论PID控制的响应速度及鲁棒性问题，考察当系统参数发生改变时，上述PID参数是否选取合适。 (Moderate purity fractionator as the object of study, taking into account the ranging molecular overflowing and non-ideal vapor-liquid equilibrium can be obtained by the transfer function between the content of light components of the overhead product Y and back to the flow L: Control Requirements: 1. integral separation PID control algorithm to control the top of the tower light component content Y 0.99 2. relay Law tuning PID parameters. tuning effect is verified: change When accused of process parameters, such as the lag time from 4 → 8, the open loop gain discussed from 3.4 → 6, the PID control of the response speed and robustness issues investigated when the system parameters are changed, the PID parameters select appropriate.)

布谷鸟搜索算法[CuckooSearch（CS）],也叫杜鹃搜索,是由剑桥大学Xin-SheYang(杨新社)教授和S.Deb于2009年提出的一种新兴启发算法CS算法通过模拟某些种属布谷鸟(CuckooSpecies)的寄生育雏(BroodParasitism)来有效地求解最优化问题的算法.同时，CS也采用相关的Levy飞行搜索机制。(Cuckoo search algorithm [CuckooSearch (CS)], also called cuckoo search algorithm is a new heuristic algorithm CS by Cambridge Xin-SheYang (Yang Novosti) professors and S.Deb proposed in 2009 by simulating some species of cuckoo Bird (CuckooSpecies) parasitic brood (BroodParasitism) effectively algorithm optimization problem. At the same time, CS also uses associated Levy flight search mechanism.)

说明：  利用matlab工具箱函数，分别画出长度为15的矩形窗、汉宁窗、汉明窗和布莱克曼窗的幅频（dB）特性曲线，观察它们的主要参数（主瓣宽度、过渡带宽度、旁瓣峰值幅度）的差别。(Matlab toolbox function is used to draw the amplit-frequency (dB) characteristic curves of rectangular window, hanning window, hamming window and blackman window with the length of 15, and observe the difference of their main parameters (main lobe width, transition band width, side lobe peak amplitude).)

Given the number of triangles N , the MATLAB function plots nested triangles.

this program is for binary shift keying.
