总体平均经验模态分解适合于分析非线性、非平稳信号序列，具有很高的信噪比。(The overall average empirical mode decomposition process)

about Accounting Version 3 This guide explains how to use Eshan Accounting accounting and enterprise resource planning (ERP) software to run your business. It focuses on things an entrepreneur or business owner needs to know and do to run a real business rather than on describing each function of the software. In fact, you won’t find every little detail about Eshan Accounting here, especially if an item seems easy enough to figure out by reading the screen. Instead, you’ll see how each feature works together to run real businesses. Some elements of an accounting system may be unfamiliar to you, especially if you don’t have an accounting background or are using an ERP for the first time. I try to explain them as I cover each one below.

用matlab编写的实现2009的2009次的大数计算的精确结果，这个题目是迅雷公司招聘时出的一道数学题目 .(Written by matlab implementation of the 2009 meeting of the large number of 2009 calculated the exact result, the topic of recruitment companies out of Thunder math topics.)

、改写例程，编制用Fisher线性判别方法对三维数据求最优方向W的通用函数。 2、对下面表3-1样本数据中的类别ω1和ω2计算最优方向W。 3、画出最优方向W的直线，并标记出投影后的点在直线上的位置(Rewriting routine, the preparation of Fisher linear discriminant method using three-dimensional data on the direction of seeking the best general-purpose function of W. 2, for the following sample data in Table 3-1 in the categories of ω1 and ω2 to compute the optimal direction of W. 3, draw the best straight line the direction of W, and mark out the projection of the points in a straight line after the location of)

在本程序中，轻松实现了阵列信号角度的估计。(In this program easily estimate of the angle of the array signal)

OSCaR是一个锥形束CT（容积CT）重建算法，为AAPM开发的一个开源matlab gui代码，其投影数据需要到官方网站下载。也可以使用varian或者医科达的cone beam ct 投影进行重建。( OSCaR is a code about the reconstruction of cone beam CT， it is GUI，and very friendly。)

对三种不同数值的RCS和雷达峰值功率，SNR相对检测距离的曲线。(RCS and radar peak power for three different values ​ ​ of the the SNR relative detection distance curve.)

matlab调用计算机声卡，实时显示计算机播放的声强级，使用数据获取工具箱，强烈推荐(call matlab computer sound cards, real-time display of the computer to play sound intensity level, the use of data acquisition toolbox, strongly recommend)
