`1-magic : Recovery of Sparse Signals via Convex Programming

说明：  用matlab实现的bp算法程序用matlab实现的bp算法程序(Bp algorithm using matlab implementation process to achieve the bp algorithm with matlab program)

该程序是基于数值分析的计算的三次样条插值和最佳平方逼近，用c做的，有注释，代码简单，希望能对您有用(The program is based on the numerical analysis of the calculated cubic spline interpolation and best square approximation, with c do, Notes, code simple, hoping to be useful for you)

基于UWT变换的去噪，利用的是硬阈值来设置阈值门限的(UWT transform based denoising, using the hard threshold to set the threshold value threshold)

《MATLAB 揭秘》为学习这种功能强大的数学计算工具提供了高效的、启发性的方法。 本书使用简单易行的风格，一开始介绍了 MATLAB 基础，你将学习到如何绘制图象，求解代数方程及计算积分，也将学习到如何求解微分方程， 求 ODE 的数值解， 使用特殊函数工作。 本书含有几百个例子及其详细解说过程，章末带有习题，书末还带最终测试题目，一句话，本书给予你的是 MATLAB 精华。 本自学指导书提供了： z 上手 MATLAB的最快方法 z 几百个带有解答过程的工作实例 z 覆盖了MATLAB7 z 每章章末配有习题，提高学习质量，查漏补缺。 z 书末附有最终测试题 z 为学习和工作节省时间提高效率 《MATLAB 揭秘》对初学者很容易，对高手有挑战性，是通往计算精度的捷径。("MATLAB Reveal" to learn the powerful mathematical tools to provide efficient and enlightening way. This book uses a simple style, the beginning describes the basis of MATLAB, you will learn how to draw images, solving algebraic equations and calculating points, will also learn how to solve differential equations, find the numerical solution of ODE, the use of special function work. This book contains hundreds of examples and a detailed explanation of the process, with the end of the chapter exercises, end of the book is also the ultimate test subject with a word, this book gives you the essence of MATLAB. This book provides a self-study guide: z fastest way to get started MATLAB z hundreds of examples of the work process with a solution z covers MATLAB7 z chapter at the end of each chapter with exercises to improve the quality of learning, leak filled. z end of the book title with a final test z for the learning and work to save time and improve efficiency "MATLAB Re)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

This function is useful to make a dateaxis adjustable

曲线拟合和多项式拟合-1，主要用于工程计算，工程优化。(Curve fitting and polynomial fitting, is mainly used for engineering calculations, engineering optimization.)
