说明：  本文件为Matlab环境下，不用小波工具箱编的小波变换源代码。(this document for Matlab environment, not wavelet Toolbox series of the wavelet transform source code.)

differential evolution

这个是一个自己做的程序，可以进行相关的操作，初学者(This is a program to do their own, can be related to the operation, for beginners)

粒子群算法的matlab代码，w是随迭代次数增加而线性递减的(particle swarm optimizer)

压缩感知理论及其研究进展,文综述了cs理论框架及关键技术问题，并着重介绍了信号稀疏变换、观测矩阵设计和重构算法三个方面的最新进展，是一篇综述。(Compression perception theory and research progress, cs paper reviews the theoretical framework and key technical issues and focuses on the latest developments signal sparse transform observation matrix design and reconstruction algorithms in three aspects, is a review.)

计算一维和二维表面粗糙度Ra，根据需要自行选择。(Calculate one and two dimensional surface roughness Ra, according to the needs of your choice.)

本代码是在matlab环境下完成的数字图像的直方图均衡化(The code is in the matlab environment to complete the digital image of the histogram equalization)

本程序按照胡广书《现代数字信号处理》书中的谱估计的内容仿真了各种经典谱估计方法以及现代谱估计方法（周期图法、BT法、welch法、自相关法、修正的协方差法、burg法），因为是课程作业，因此逻辑上写得十分简洁，适合初学者参考。(The program in accordance with the Hu-book of modern digital signal processing book spectral estimation simulation the various classical spectrum estimation methods, as well as the modern spectral estimation methods (periodogram, BT France, welch method, auto-correlation method, the modified covariance method , burg method), because the course work, so logically written very simple for beginners.)
