gmdh神经网络的详细程序，demo是主程序源码。(gmdh detailed procedures for neural networks, demo is the main source.)

史密斯圆图的应用, 包括阻抗匹配，计算方法等(Smith chart applications, including impedance matching, calculation methods)

Compare<T> implements IArgumentMatcher.

包括面积、周长、矩形度、伸长度，毕设内容，高光谱图像基本处理，可以提取一幅图中想要的目标。( Including the area, perimeter, rectangular, elongation, Complete set content, basic hyperspectral image processing, Target can be extracted in a picture you want.)

1.对染噪doppler信号进行小波包3层分解：分解层次j=1,2时，都是信号的概貌；当j=3时，反映概貌的已几乎不含噪声分量，而其它噪声分量的幅值已很小。 2.对加噪Blocks信号进行不同阈值及不同阈值的使用方式降噪。 (1. On noise pollution doppler signal decomposition of wavelet packet Layer 3: decomposition level j = 1,2, are the signal profiles when j = 3 to reflect the general picture has been almost non-noise component, while other noise components amplitude has been very small. 2. Blocks of noise signals of different thresholds and different thresholds for the use of noise reduction methods.)

This is the explanation about the data encryption, and this can be mostly used in the stegnography and cryptography, This encrypts the data such as image or any data file and can be used in hiding.

说明：  这个程序是使用MATLAB对ofdm中的压缩扩张技术降低PAPR技术的仿真，程序仿了不同u值下的对PAPR的降低程度不同(that is a simulation of papr using matlab ,it is using u_law companding)

说明：  离散数据的快速傅里叶变换。读取一段数值模拟得到的时间历程曲线，进行fft变换，得到幅频曲线。(Fast Fourier transform of the discrete data. Read the section of numerical simulation of the time course of the curve, fft transform, the amplitude-frequency curve.)

一个基于LBM颜色模型的MATLAB算法编程，以便针对LBM颜色模型的求解。(A MATLAB programming algorithm based on LBM color model, so that for LBM color model to solve.)

说明：  matlab语言编写的 大地电磁电阻率正演程序(matlab language MT resistivity forward procedure)
