m-file matlab for backward toward powerflow

物理光学主要内容的仿真模拟，如双缝干涉，牛顿环现象，夫琅禾费衍射，菲涅尔衍射等(The main content of the physical optics simulation, such as the double-slit interference phenomenon of Newton' s rings, Fraunhofer diffraction Fresnel diffraction)

Analyzing 2-opt for Traveling Salesman problem (TSP)

function [r_path, r_cost] = dijkstra(pathS, pathE, transmat) The Dijkstra s algorithm, Implemented by Yi Wang, 2005 This version support detecting _cyclic-paths_

本程序用于观察数字信号处理中的吉布斯现象，有助于加深对窗与信号截断的理解(Change the length of the window and observe the Gibbs phenomenon)

说明：  该程序为盲信号中的盲卷积程序，给大家个参考(The program for the blind signal in the blind deconvolution process, give us a reference)

包含多种噪声谱估计算法用于语音增强，采用的是标准谱减法，主要用于对各种噪声谱估计算法对比，详见readme.txt(Ppls spectral subtraction noise spectrum estimation, mainly used to compare the performance of different noise spectrum estimation algorithms, including Martin s minimum tracking algorithm, Minimum controlled recursive average algorithm (Cohen), variant of Minimum controlled recursive average algorithm, improved Minimum controlled recursive average algorithm (Cohen ), continuous spectral minimum tracking (Doblinger), weighted spectral average (Hirsch & Ehrilcher), connected frequency regions (Sorensen & Andersen). See readme.txt inside)
