这个程序是关于图像的方针，直方图方法； 画出直方图。(This program is about the principle of the image, histogram method draw histogram.)

说明：  此程序是关于小波变换用于故障信号分析和处理的程序。(this procedure is used on the wavelet transform fault signal analysis and processing procedures.)

函数dB=PSNR(F,G),返回图像F相对于图像G的信噪比峰值.用于全息图后期处理中的参考.测试通过(Based of the formular dB=PSNR(F,G),it returns peak signal-to-noise ratio (dB) of image F with respect to G.)

说明：  please give the matlab codings

tvp-var model 可以用来做TVP-VAR模型(tvp-var model for good use)

此书包含图像处理的各种函数命令和解析，读者一看就能明白！！！(This book contains various functions of image processing commands and parsing, the reader can understand a look! ! !)

用Parzen窗法或者kn近邻法估计概率密度函数，得出贝叶斯分类器，对测试样本进行测试，比较与参数估计基础上得到的分类器和分类性能的差别.2． 同时采用身高和体重数据作为特征，用Fisher线性判别方法求分类器，将该分类器应用到训练和测试样本，考察训练和测试错误情况。将训练样本和求得的决策边界画到图上，同时把以往用Bayes方法求得的分类器也画到图上，比较结果的异同。3．选择上述或以前实验的任意一种方法，用留一法在训练集上估计错误率，与在测试集上得到的错误率进行比较。(Use Parzen Windows method or the kn neighbor method estimated probability density function, draw the bayes classifier, to test sample to test, and the parameter estimation is based on the classifier and get the difference of classification performance. 2. At the same time the height and weight data as the characteristic, with Fisher identification method for linear classifier, and the application of the classifier to training and test sample, investigation and test training error condition. Will the training sample and utility of decision on the drawing boundary paint, and at the same time before the Bayes method with optimal classifier also paint chart, the result of the comparison of the similarities and differences. 3. Select the above or before any a kind of method of experiment, with a method for training set in the estimation error rates, and on the test set get error rates are compared.)

（7，4）系统循环码编码器 code_out = cyclic_coder(code_in) 该系统循环码编码器的生成多项式是g(x) = x^3 + x + 1 输入参数code_in是信息码字，是1×4的行向量；输出code_out是编码后的系统 循环码字，是1×7的行向量。 函数运行时，同时画出输入信息码字和循环码字的波形图。( (7,4) cyclic code system Encoder code_out = cyclic_coder (code_in) cyclic code encoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 of information input parameters code_in code word is 1 × 4 row vector output code_out System is encoded codeword cycle, the row is 1 × 7 vector. Function to run at the same time draw the input code word and code word cycle waveform.)

hello,to growing the picture in matlab

说明：  原作者编写的灰狼算法matlab代码，简单易懂。(The gray wolf algorithm matlab code written by the original author is simple and easy to understand.)
