说明：  整个系统分为数据采集和数据分析两大部分，以友好的图形界面与用户进行交互沟通。 声音数据采集部分实现数据采集功能,根据用户选择的采样频率和预设的采样时间来从声卡获得用户需要的数据。并且将采集到的数据及其频谱图以图形方式很直观的呈现于用户面前。 图像采集分析部分，读入图像后，根据选择，对其进行Linear Conformal、Affine、Projective、Polynomial、Piecewise Linear、Sinusoidal、Barrel、Pin Cushion变换(The whole system is divided into data collection and data analysis of two parts, with a friendly graphical interface to communicate with the user interaction. Sound data collection part of the data collection function, according to user-selected sampling frequency and sampling time to the default user from the sound card to obtain the data needed. And the collected data and the spectrum is very intuitive graphically presented in front of the user. Image acquisition and analysis section, read the image, based on the choice of its Linear Conformal, Affine, Projective, Polynomial, Piecewise Linear, Sinusoidal, Barrel, Pin Cushion Transformation )

数字信号处理实现滤波器的功能，此程序中有几个滤波器的实现(Digital signal processing filter function, this procedure several filter)

信号傅里叶变换的matlab程序，包括对幅频和相频的图形绘制(Signal Fourier transform matlab program, including the magnitude and phase frequency of the graphics rendering)

"Magic" Reconstruction: Compressed Sensing.

说明：  整个ofdm系统仿真的全过程，包括qpsk的调制解调等(The whole process of OFDM system simulation, including QPSK modulation and demodulation)

非常有用的学习资料，用它学习matlab，从入门到精通，面面俱到(Very useful learning materials, use it to learn matlab, from entry to the master, everything)

说明：  研究碳纳米管的热输运，其中输运系数最重要，此程序的功能就是计算透射系数(Study the thermal transport of carbon nanotubes, in which the most important transport coefficients, this procedure is the calculation of the function of transmission coefficient)

生成30位的m序列的matlab仿真源代码(M-generated sequence of 30 simulation source code matlab)

近年来，盲源分离技术成为研究热点。这是盲源分离技术的JADE算法，十分经典哦(In recent years, blind source separation technique to become a research hotspot. This is the JADE algorithm for blind source separation, very classic!)
