iris with matlab.irisData is 150x5. row: Sepal.Length Sepal.Width Petal.Length Petal.Width Group(1,2,or 3) the first 50x5 is Isis-setosa(1), the second 50x5 is Isis-versicolor(2), the last 50x5 is Isis-virginica(3). !!! Caution !!! X(50 + 21, :) equals X(50 + 50 + 27, :), but Y(50 + 50 + 21) DOESNOT equal Y(50 + 50 + 27)! So the algorithm will NEVER be 100 correct.

利用直接法、间接法、以及Bartlett窗及Hamming窗下的Welch法进行功率谱分析(Using the direct method, indirect method， and the Bartlett window and a Hamming window in the Welch method for power spectral analysis)

说明：  时间序列分析中参数估计方面的实现,在matlab环境下实现的代码(parameter estimation)

格兰杰因果关系检验 matlab和C的源代码，可以直接输入(Granger causality test matlab and C source code can be entered directly)

cvx, matlab程序包，主要基于凸优化理论的优化程序包(cvx convex optimization)

双目视觉三维重建程序，输入左右相机匹配点对矩阵，自动计算投影矩阵，并输出射影空间下的三维点坐标(Binocular vision three-dimensional reconstruction program, enter the matching points on the matrix around the camera to automatically calculate the projection matrix, and output under the three-dimensional projective space point coordinates)

本文根据对原始纯净图像进行的椒盐加噪处理，提出了利用中值滤波法消除图像噪声的实用方法。使用软件工具MATLAB快速地实现了图像的中值滤波。(According to the original purity of the salt and pepper plus noise image processing, proposed by using median filter to reduce image noise and practical method. MATLAB software tools used to achieve fast median filtering of images.)

PSO theory explanation

本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法。此文件为turbo码译码一般的MAP算法，程序中用作与咬尾turbo译码的对照(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm. This document is a general MAP turbo decoding algorithm, and biting the end of the program for the control turbo decoding)
