具有高分辨信号的空间谱估计算法——MUSIC（另一种写法）(MUSIC)

在matlab的环境下，运行此程序可将两段音频信号进行叠加(In the matlab environment, run this program can be two audio signals are superimposed)

说明：  matlab 教程 很有用的啊(matlab tutorial useful ah)

数字信号处理与题解。DSP理论入门电子书，书中有简单的Matlab编程，以及简单的滤波器设计(Digital signal processing and problem solution. Introduction to DSP theory book, the book has a simple Matlab programming, and simple filter design)

本程序利用奇异值分解对3通道彩色图像进行压缩分解，具体步骤如下： 压缩过程： 1. 选取子图像大小K值，把图像分解成M×M个子图像，IMG(s),s=1,2,…, M2，其中M=N/K，原始图像IMG大小为N×N。 2. 计算这M2个子图像的平均值average，对每幅子图像减去均值图像得到新图像。 3. 计算相关矩阵R，其元素定义为 。 4. 计算R的特征值与特征向量，计算每幅子图像与最大特征向量的内积，便得到编码，即压缩后的图像。 (This procedure using singular value decomposition of 3-channel color image compression decomposition, concrete steps are as follows: compression process: 1. Select the sub-image size K value, the image is decomposed into M × M sub-image, IMG (s), s = 1, 2, ..., M2, in which M = N/K, the original image IMG size N × N. 2. M2 calculate the average of sub-image average, for each sub-image minus the new images mean images. 3. Calculation of correlation matrix R, defined as its elements. 4. Calculation of the characteristics of R value and eigenvector calculated each sub-image with the largest eigenvector of the inner product, they will have to code, that is, the compressed images.)

小波去噪的matlab程序。有三种阈值选择方法：标准的，强制的，自己设置的。(Wavelet denoising matlab program. There are three kinds of threshold selection method: standard, mandatory, set up their own.)

针对光纤耦合数据文件在邦加球上处理显示，是偏振态变化更加清晰可见。(According to data files in the state, fiber coupled with ball processing and display, polarization more change is clearly visible.)

股票指数模拟为几何布朗运动，GBM。 参数有五个： s0，dt（time step），均值，标准差，到期时间T； 利用子函数进行10万条轨道的monte carlo 模拟到期日（3个月）的指数点数，从而估计在买入信号出现后，3个月后的损益情况，主要用来估算VAR (Financial risk analysis on Matlab monte carlo simulation, stock index simulation for geometric Brownian motion, GBM. )
