数字信号处理的视频分析中短时傅立叶变化STFT和连续小波变化CWT和离散小波变换DWT的算法源程序,在实际中已应用,(digital video signal processing of short-time Fourier analysis of changes STFT and continuous wavelet transform CWT and DWT DWT algorithm source, in practice has been applied.)

说明：  有限元方法编程matlab程序源代码，很好的(Finite element method matlab programming source code, well)

这是一个检测和匹配SIFT特征点的演示算法，同时还包含一个C程序用于载入特征点来做简单的特征匹配。(This is a detection and matching SIFT feature point presentation algorithm, but also contains a C program used to load the feature point to do a simple feature matching.)

本书以MATLAB R2012a为编写基础，系统讲解MATLAB基本环境和操作要旨；分章阐述符号计算、数值计算、计算结果可视化及编程精要；选例展现MATLAB精华工具SIMULINK的功能级和元器件级仿真能力；范例剖析MATLAB版面编辑器的用法和图形用户界面的制作要领；简扼勾画MATLAB和WORD集成一体的Notebook环境。(This book is written in MATLAB R2012a based system to explain the basic MATLAB environment and operating gist sub chapter on symbolic computation, numerical calculation results visualization and programming essentials selected cases demonstrate functional level and component-level MATLAB SIMULINK simulation tools cream ability layout editor MATLAB analysis paradigm production essentials usage and graphical user interface Jane briefly outline one integrated MATLAB and WORD Notebook environment.)

rssi定位算法，极大似然估计法，最小二乘法，代码，极大似然估计法(rssi localization algorithm)

MUSIC算法是最经典的超分辨DOA估计方法，它利用了信号子空间和噪声子空间的正交性，构造空间谱函数，通过谱峰搜索，检测信号的DOA。MUSIC算法对DOA的估计从理论上可以有任意高的分辨率(MUSIC algorithm is the most classical super-resolution DOA estimation method. It uses the orthogonality of signal subspace and noise subspace to construct spatial spectral function, and detects the DOA of signal through peak search. MUSIC algorithm can theoretically estimate DOA with arbitrary high resolution.)

说明：  离散型PSO matlab，供大家日常学习、测试使用。谢谢(Discrete PSO matlab.It can be used for daily study and test. thank you)

说明：  用matlab编程实现一些最优化问题的求解，运筹学中的问题(Matlab programming to realize some of the most optimization problems, the problems in Operations Research)

matlab file is use to just liquild volumn, now need you to help check it.
