数字信号处理教程MATLAB释义与实现（电子工业出版社）程序集(signal processing leture notes. matlab implement )

本辞典紧跟MATLAB发展的动态。搜集整理了1 000余条MATLAB的使用函数，以英文字母的先后顺序进行排序，在介绍每个函数的过程中，分别介绍了函数的语法、描述、应用实例以及与之相似的函数，可以让用户在学会一个函 数的同时，触类旁通地领会其他类似函数的用法，让用户更全面地掌握MATLAB的知识，在进行MATLAB开发时能方便快捷地查询到相关函数的使用方法。(The Dictionary of keeping up the MATLAB development dynamic. Has collected more than 1,000 more than the MATLAB use function, sort the order of the letters of the alphabet, introduced the process of each function, function syntax, description, application examples as well as the similar function, allows users learn a function at the same time, by analogy to understand the usage of other similar functions, allowing users to better grasp the knowledge of MATLAB In MATLAB development can quickly and easily query to the use of the correlation function.)

　传统的信号理论，是建立在Fourier分析基础上的，而Fourier变换作为一种全局性的变化，其有一定的局限性。在实际应用中人们开始对Fourier变换进行各种改进，小波分析由此产生了。小波分析是一种新兴的数学分支，它是泛函数、Fourier分析、调和分析、数值分析的最完美的结晶；在应用领域，特别是在信号处理、图像处理、语音处理以及众多非线性科学领域，它被认为是继Fourier分析之后的又一有效的时频分析方法。 小波变换与Fourier变换相比，是一个时间和频域的局域变换因而能有效地从信号中提取信息，通过伸缩和平移等运算功能对函数或信号进行多尺度细化分析（Multiscale Analysis），解决了Fourier变换不能解决的许多困难问题。(The traditional signal theory, is based on Fourier analysis based on Fourier transform, and as a kind of global change, it has some limitations. In the actual application of Fourier transform people began to various improved, wavelet analysis produced. Wavelet analysis is a new branch of mathematics, it is functional, Fourier analysis, harmonic analysis, numerical analysis of the crystallization of the most perfect In the fields of application, especially in signal processing, image processing, audio processing as well as many nonlinear scientific fields, it is considered to be the Fourier analysis after another effective time-frequency analysis method. Wavelet transformation and Fourier transform, compared is a time and frequency domain and the local transform can effectively extract information from signal, through the telescopic peace shift etc operation function of the function ? )
