Matlab code for Direction of Arrival estimation

用于计算二维光子晶体（用于计算二维光子晶体）(Used to calculate the two-dimensional photonic crystals (used to calculate the two-dimensional photonic crystal))

实现Gabor滤波的源代码，包括C++、matlab源程序，Gabor提取图像特征原理及其matlab实现。(Gabor filtering source code, including C + +, matlab source code, Gabor extract image features principle matlab.)

对二维图像进行离散傅里叶变换，分别给出了直流分量移动到频谱中心前后的频谱图样。(Two-dimensional images of the discrete Fourier transform, respectively, given the spectrum to move to the DC component of the spectrum before and after the design center.)

用Matlab实现的人脸检测算法. Based on the paper: Face Detection using Local SMQT Features and Split Up SNoW Classifier(Face Detection algorithm for Matlab. Based on the paper: Face Detection using Local SMQT Features and Split Up SNoW Classifier)

This program is a new way to estimate the coherence function. It s based on the MVDR and is much more reliable than the classical Welch s method implemented in MATLAB. There are 2 programs: the main program called coherence_MVDR.m and and an example, called illustrate.m, that calls the main function to show how it works. There also included 2 papers that we published on this algorithm. (This program is a new way to estimate the coherence function.

matlab编写的调整svm参数的程序，其中cross是主程序，另两个是自己编写的svm核函数，如果要用matlab自带的核函数就把-t的值改成2即可。Ytrain是标记矩阵，Xtrain是特征矩阵，都由用户自己导入。可利用k倍交叉验证来选择最优的c参数。k可自行更改。(svm matlab prepared to adjust the parameters of the program, which cross the main program, and the other two are themselves prepared svm kernel function, if you use the value of the kernel function matlab own put-t can be changed to 2. Ytrain is labeled matrix, Xtrain is characteristic matrix, imported by the users themselves. K-fold cross-validation can be used to select the optimal c parameter. k can make changes.)

主要用于NOLS环境下网络定位，里面总结了fang、laylor等算法，非常实用(Mainly used for NOLS network environment, which summarizes the Fang, laylor and other algorithms, very practical)

利用matlab编程计算矩阵的协方差，对数学建模很有用(slove mathematics things)
