MATLAB命令大全 人民邮电出版社出版 每个命令都有实例，简单易学(MATLAB command the Daquan People s Post published have each command instance, easy to learn)

粒子群改进算法，有助于学生学习,可以在此基础上改进(Improved particle swarm algorithm to help students to learn, you can improve on this basis)

用MATLAB程序软件完成Z-N法对控制器的参数整定，实现P,PI,PID控制器的分别参数整定，并求出控制器的控制参数Kp，Ti，Td。最后绘制出不同控制器控制下的及参数整定前后的单位阶跃响应图进行比较。(MATLAB program software is used to complete the parameter tuning of the controller by Z-N method. The parameters of P, PI, PID controller are adjusted, and the control parameters of the controller Kp, Ti, Td are obtained. Finally, the unit step response diagram before and after parameter tuning is plotted under different controller control.)

Matlab 6.5 finding is it a signal a FSK modulated.

matlab实现的史密斯圆图 可以用来辅助其他程序(Smith chart)

最优化中的一种方法，amijo方法，该方法很典型，(Optimization of a method, amijo method, which is typical,)

implementation of fuzzy logic of vector control

spwm 中频机组仿真,可以仿真整个过程,包括谐波干扰(spwm IF unit simulation, can simulate the whole process, including the harmonic interference)

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.
