Newton-Raphson算法 介绍
在科学计算和财经工程领域,许多数值算法都是通用的(至少在理论上是),可广泛地用于解决一类问题。一个大家熟悉的例子就是Newton-Raphson例程,它可用来寻找方程 f(x)=0的数值解。标准的数学表达式f(x)表示f是变量x的函数,其通常的表达形式为f(x,a,b,...)=0,f被定义为多于一个变量的函数。在这种情况下,Newton-Raphson算法试图把x以外的变量固定并作为参数,而寻找关于变量x的数值解。
由于Newton-Raphson算法需要知道被求解函数的确切表达,其传统实现方法是直接将代码嵌入到客户应用程序中。这就使得算法的实现代码经过针对不同被求解函数的少量修改后在客户程序中反复出现。
同许多其它数学例程一样,Newton-Raphson算法的具体实现是应该与特定用户无关的。并且,重复编码在任何情况下都应该尽量避免。我们很自然地会想到把该类例程作为库函数来实现,以使客户程序可以直接调用它们。但是,这种实现方式必然会涉及到如何将用户自定义函数(Newton-Raphson 例程需要调用该函数)封装成可以作为参数传递的形式。

Research-on-Compressed-Sensing
经典的香农采样定理认为,为了不失真地恢复模拟信号,采样频率应该不小于奈奎斯特频率(即模拟信号
频谱中的最高频率)的两倍.但是其中除了利用到信号是有限带宽的假设外,没利用任何的其它先验信息.采集到
的数据存在很大程度的冗余.Donoho等人提出的压缩感知方法(Compressed Sensing或Compressive Sampling,
CS)充分运用了大部分信号在预知的一组基上可以稀疏表示这一先验信息,利用随机投影实现了在远低于奈奎斯
特频率的采样频率下对压缩数据的直接采集.该方法不仅为降低采样频率提供了一种新思路,也为其它科学领域
的研究提供了新的契机.该文综述性地阐述了压缩感知方法的基本原理,给出了其中的一些约束问题和估计方法,
并介绍压缩感知理论的相关问题———矩阵填充,最后讨论了其未来可能的应用前景.
(According to the conventional Shannon s sampling theorem,in order to represent the
analog signal,the sampling rate should not be less than twice the Nyquist sampling rate.Howev-
er,this theorem only makes use of the bandwidth information.As a result,the collected data
contain many redundant information.The recently proposed sampling method,compressed sens-
ing or compressive sampling(CS),can collect compressed data at the sampling rate much lower
than that needed in Shannon s sampling theorem by exploring the compressibility of the signal.
This paper presents a review on the basic theory of CS.Some of the restrictions and recovery
methods in CS are also discussed.Finally,some potential applications based on CS are presented.
