PN序列生成函数, 测试代码. 带有一组生成多项式(failed to translate)

说明：  本源代码可以对提取的光强度信息转换为频域信息，可以做分析之用(Origin of the code can be extracted light intensity information is converted to frequency domain information and analysis can be done with)

在轴箭头绘制坐标空间是很困难的，因为Matlab的内置函数图工程箭头坐标空间。这个函数的轴到图坐标计算及放置在正确的位置注释箭头。它还提供了一个按钮式功能重新同步线和箭头如果调整轴或人物，或变更线的属性。(Plotting an arrow in axis coordinate space can be difficult, since Matlab s built-in arrow function works in figure coordinate space. This function does the axis-to-figure coordinate calculation and places an annotation arrow in the correct location. It also provides a button-down function to re-sync the line and arrow if you resize the axis or figure, or change the line properties.)

包括种群初始化、选择、交叉、变异各个子程序，每一部分都作为一个单独M文件。主程序是实现遗传算法网络的训练过程；测试程序可以对训练得到的网络进行结果测试(Including population initialization, selection, crossover and mutation all subroutines, each of which as a separate M-file. Main program is to achieve genetic algorithm network training process test procedures can be trained to get the results of the test network)

无监督混合高斯模型（GMM）的EM估计，含两篇IEEE论文的源码(This is a set of MATLAB m-files implementing the mixture fitting algorithm described in the paper M. Figueiredo and A.K.Jain, "Unsupervised learning of finite mixture models", IEEE Transaction on Pattern Analysis and Machine Intelligence, vol. 24, no. 3, pp. 381-396, March 2002.)

—The minimum variance distortionless response (MVDR) approach is very popular in array processing. It is also employed in spectral estimation where the Fourier matrix is used in the optimization process. First, we give a general form of the MVDR where any unitary matrix can be used to estimate the spectrum. Second and most importantly, we show how the MVDR method can be used to estimate the magnitude squared coherence function, which is very useful in so many applications but so few methods exist to estimate it. Simulations show that our algorithm givesmuchmore reliable results than the one based on the popular Welch’s method.
