matlab code for tube count determination shell and tube heat exchanger..remain part will be uploaded

本程序可以实现QAM均衡，这里面有详细的英文说明，对于复数仿真很有用处(QAM balance can be achieved, there is a detailed statement in English, the plural useful simulation)

熵（近似熵，样本熵）,适合初学者。值得一看。。。。。(Entropy (entropy of approximate entropy, sample), suitable for beginners. Worth a look... )

对信号进行扫频，可以利用程序一次性读出所用频率的幅值和相位(Sweep the signal, you can use the program at once read out the frequency with amplitude and phase)

一本很好的matlab零起点学习手册，通过该手册可以逐步掌握matlab的编程方法(A very good learning manual matlab beginners, step by step through the manual to master the programming method matlab)

this is a code in matlab for character recognition depending on correlation

说明：  关于超宽带（UWB）一些信道的matlab仿真程序。(On ultra-wideband (UWB) channel matlab simulation of some procedures.)

对有类别监督的数据进行先行判别分析用于降维 数据为结构体类型，返回数据也是降维后的结构体类型。如(a.X a.y)a.X是带有类别的数据，a.y是类别信息(Synopsis: model = lda(data) model = lda(data,new_dim) Description: This function is implementation of Linear Discriminant Analysis. The goal is to train the linear transform which maximizes ratio between between-class and within-class scatter matrix of projected data.)

计算信号的希尔伯特-黄变换。 将HHT.m中的sig改成需要计算的信号即可。(Calculating signal Hilbert- Huang Transform. )

1)把您的联系电话号码 通过DTMF 编码生成为一个 .wav 文件。 2)对所生成的DTMF文件进行解码(1) put your contact phone number via DTMF codes generated as a. Wav file. 2) files generated by the DTMF decoder)
