说明：  分别用中心极限定理和box-muller法生成高斯噪声(Central limit theorem were used to box-muller method and the Gaussian noise generated)

该代码实现的是压缩感知理论中的信号恢复问题。将压缩感知理论中的信号恢复问题转化为带参数约束的回归问题，从而利用贝叶斯理论实现参数估计，从而得到高效的重建稀疏信号。(The code to achieve the signal recovery problems in the theory of compressed sensing. Recovery issues into regression problems with parameter constraints will signal compression perception theory, Bayesian theory parameter estimation, resulting in efficient reconstruction of sparse signal.)

说明：  边缘检测是图形图像处理、计算机视觉和机器视觉中的一个基本工具，通常用于特征提取和特征检测，旨在检测一张数字图像中有明显变化的边缘或者不连续的区域，在一维空间中，类似的操作被称作步长检测（step detection）。(Edge detection is a basic tool in graphics and image processing, computer vision and machine vision. It is usually used for feature extraction and feature detection. It aims to detect the edge or discontinuous area with obvious changes in a digital image. In one-dimensional space, similar operations are called step detection)
