信号分析与处理—MATLAB语言及应用,,介绍matlab在信号分析中的应用，，讲得不错(Signal Analysis and Processing-MATLAB language and application, introduction matlab in signal analysis applications, put it well)

测试文本，选用著名的gettysburg这篇英文文本做为测试文本(Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. In the end, the cosine similarity of texts is used to measure the similarity between the query and documents.)

说明：  一个很好的求信号包络的MATLAB工具包.(A good demand signal envelope of MATLAB tool kit)

说明：  蒙特卡罗方法可以有效地解决复杂的工程问题，而MATLAB具有强大的数值计算功能。将二者结合使用，可以得到高效的解决问题的方法。本文阐述了该方法并通过实例验证了该方法的正确性和优越性。 (Monte Carlo method can effectively solve complex engineering problems, and MATLAB has powerful function of numerical calculation. The two in combination, can be cost-effective solution to the problem. This paper describes the methods and examples of the method to verify the correctness and superiority.)

Understanding Interference Effect in communication systems.

The PSNR is most commonly used as a measure of quality of reconstruction of lossy compression codecs (e.g., for image compression). The signal in this case is the original data, and the noise is the error introduced by compression

此程序是一种有效的插值算法，对离散数据插值所得结果精确度高且比较平滑。(This procedure is an effective interpolation algorithm, the discrete data of the interpolation results obtained are accurate and relatively smooth.)

Stephen J.Chapman《MATLAB编程（第二版）》英文影印版的中文译本，这本书对初学者很好的入门教材。(Stephen J.Chapman "MATLAB Programming (second edition)," the English version of the Chinese translation of photocopying, this book is a good primer for beginners.)
