NA解TSP,操作环境matlab 附中文注释(program of NA to solve tsp)

this is matlab code for the home work assignment. it will be help ful to some guy

Hi this is a gbvs file. this is a matlab file

matlab在工程数学中的应用，适合初学者学习(matlab application of mathematics in engineering, suitable for beginners to learn)

说明：  运用matlab求矢量x的均值和方差。代码实现简单，运行正确(Using matlab find the mean and variance of the vector x. Code is simple, right)

交流位置伺服系统因其存在参数时变、负载扰动以及电机的非线性等缺点， 很难为其建立准确的模型. 模糊（ fuzzy）控制具有无需建立被控对象的数学模型、鲁棒性好等 优点，但稳态精度差. 将模糊控制和PID 控制相结合，设计了Fuzzy-PID 双模控制器. 在论域内 用不同的控制方式分段实现控制，这样就综合了模糊控制和PID 控制的优点，克服了各自的缺 点. 该控制器结构简单、易于实现. 在半闭环交流位置伺服系统上所做的实验表明，采用Fuzzy- PID 双模控制器与采用经典PID 控制器相比，阶跃响应的调整时间减少了33. 7 ，并且无超 调，轨迹跟踪误差减小了47. 2 .(AC servo system because of the presence of parameter variations, load disturbances and non-linear motors and other shortcomings, it is difficult to establish accurate models for fuzzy (fuzzy) control without having to build a mathematical model of controlled object, robustness and good However, steady-state accuracy is poor. fuzzy control and PID control are combined to design a dual-mode Fuzzy-PID controller in the sub-region to achieve control on the different control methods, so that a combination of fuzzy control and PID control advantages to overcome their disadvantages. simply the controller structure, easy to implement. experiments on semi-closed loop AC servo system did show that the Fuzzy-PID controller is compared with the classic dual-mode PID controller, step response The adjustment time is reduced by 33.7 , and no overshoot, tracking error is reduced 47.2 .)

在matlab环境中分析FFT原理，认真看看，很快就可以掌握FFT哦(Analysis of the FFT principle in the Matlab environment, take a serious look, can quickly grasp the FFT.)

In this program we calculate the scattering field of a infinite dielectric cylinder by two methods. 1)Moment 2)Analytic

本程序的功能是：程序复位后，数码管从0开始显示数字，直到99，然而又从0到99循环显示(control the digital led from 0 to 99,then back to 0 and repeat 0 to 99.)

基于Matlab的多孔算法提取图像边缘,可以更好地提取图像边缘(Edge extraction porous algorithm based on Matlab)
