任务：
1） 借助MATLAB画出误差性能曲面和误差性能曲面的等值曲线（参考PPT2.1第17页的两幅图）；
2） 写出最陡下降法以及LMS算法的计算公式（取 ）；
3） 用MATLAB产生方差为0.05, 均值为0白噪音S(n)，并画出某次采样得到的波形（即产生任意一个噪声随机序列）；
4） 根据 2）中的公式，并利用 3）中产生的S(n)，在 1）中的误差性能曲面的等值曲线上叠加画出采用最陡下降法以及LMS法时H(n)的在叠代过程中的轨迹曲线（参考PPT2.1第17页的右下图的曲线1和曲线2）。
5）用MATLAB计算并画出LMS法时 随时间n的变化曲线（对应S(n)的某一次的一次实现）和e(n)波形；
注意：某一次实现的结果并不能从统计的角度反映实验的结果 的正确性，为得到具有统计特性的实验结果，可用足够多次的 实验结果的平均值作为实验的结果。用MATLAB计算并画出 采用LMS法时，J(n)的100次实验结果的平均值随时间n的变 化曲线（即 生成随机噪声信号并计算结果，重复执行100次， 求平均结果）。
6）在 1）中的误差性能曲面的等值曲线上，叠加画出采用LMS法得到的100次实验中的H(n)的平均值的轨迹曲线；

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

CS_OMP
该文档是一个比较简单的能够获得压缩感知稀疏解的matlab代码-OMP(正交匹配追踪)，
通过离散傅里叶变换将时域接收信号变换到频域上，
得到接收信号的频域稀疏表示，通过OMP算法，求出稀疏解，
并通过重构信号误差衡量该算法代码的精确度。(This document is a simple matlab code -OMP (Orthogonal Matching Pursuit algorithm) by which the sparse solution of compressed sensing can be obtained.
Firstly, signals received are transformed from the time domain to the frequency domain by the discrete Fourier transform.
Secondly, sparse solutions of received signals are obtained by OMP algorithm.
Finally, reconstruction error depicts the accuracy of the algorithm.)
