pid是个很实用的matlab模块，大家学习啊(pid)

对通信中应用较多的自适应滤波算法LMS算法进行了仿真，并且解决了信号的起始值的对齐问题。(Application of communication are more adaptive filtering algorithm for simulation of LMS algorithm, and solve the initial value of the signal alignment problems.)

this code shows the new filter application ........................................

在二维空间里有两个点A=(X1，Y1)和B=(X2，Y2)，如果X1>X2并且Y1>Y2 ，我们认为A优于B，A是这个集合的最大极值点，在给定的二维空间里的N个点的集合S中，找出最大极值点。(In two-dimensional space, there are two points = A = (X1, Y1) and B (X2, Y2), if the X1 and Y1 > X2 > Y2, we think that A is superior to B, A is the biggest extreme value point of the set, in A given set of N points in the two-dimensional space S, find out the most extreme value point.)

本程序是利用全有全局搜索能力的遗传算法来优化bp神经网络的，优化神经网络的权值与阈值(This procedure is the use of all-global search capability of genetic algorithm to optimize bp neural network optimization neural network weights and thresholds)

给出SISO信道的室内模型，IEEE802.11传播过程、机制，matlab实现代码及仿真(802.11 MODEL)

产生正态变量的随机数,进行未知参数的区间估计 产生两个正态总体的随机数, 进行未知参数均值差,方差比的区间估计.( generate normial variable, estimate unknown paramatric interval )

给灰度图加入白噪声和椒盐噪声，并设计了几种去噪的算法实现对噪声的降低(Adding white noise to the grayscale and salt and pepper noise, and designed several denoising algorithm for noise reduction)

图像相似判断matlab用于两个图片的相似度进行比较和分析，一个采用巴氏系数计算法。另外一个rfg越接近1则越相似(matlab similar )
