频谱分析的一个程序，分析细致！！研究频谱分析的可以可直接使用。 (Spectrum analysis of a program, and detailed analysis. ! Spectrum analysis can be used directly.)

求解的长直接地金属槽和平板电容中的电场，并画出等位线分布图(Calculation of Electron Physics )

基于matlab的音频分组器设计，里面有详细代码，简单易懂(Matlab audio packet-based design, which has a detailed code, easy to understand)

快速FOURIER变换滤波，可进行高通滤波，低通滤波，带通滤波。(rapid etween transform filtering, high-pass filter, low-pass filter, band-pass filtering.)

说明：  基于SFM的三维重建MATLAB程序，值得借鉴(SFM - based three - dimensional reconstruction of MATLAB procedures, worthy of reference)

该书系统地介绍了matlab在小波分析中使用方法，简单地介绍了小波分析的原理，及采用matlab如何实现小波分析!(The book systematically introduces matlab in the use of wavelet analysis method, a simple introduction to wavelet analysis theory, and the use of wavelet analysis matlab how to achieve!)

matlab相关知识，关于一些Matlab实用的小结之类的汇总(matlab knowledge about some Matlab Summary summary)

这部分代码主要实现了TURBO码的编解码，运用max-log-map译码方法进行译码(this code realise the encode and decode function of turbo,the decoding algorithm is by max-log-map)

运用Matlab语言编程，进行信号分析的能力。音频信号是一种连续变化的模拟信号，计算机只能处理和记录二进制的数字信号，由自然音源而得的音频信号必须经过采样，量化和编码，变成二进制数据后才能送到计算机进行再编辑和存贮，通过本实验中了解模拟信号采样和重构的完整过程，加深对采样定理的理解。(Matlab programming language to use for signal analysis. Audio signal is a continuous change of the analog signal, the computer can only handle and record the binary digital signal, derived from natural sources of the audio signal to be sampled, quantification and encoding binary data into a computer in order to re- editing and storage, through this experiment to understand the analog signal sampling and reconstruction of the full process, to deepen understanding of the sampling theorem.)

这是一个半光滑牛顿法解决图像复原问题的MATLAB算法(semi-smooth newton method for image restoration)
