著名的数学软件Matlab,Mathematica,Maple中文教程，对从事数学计算仿真的工程师非常有帮助！(Chinese tutorial mathematics software known as Maple ,Matlab and Mathematica, is very helpful for mathematical simulation engineer! )

直流潮流计算程序（作者FX）提供7种控制方式，导纳矩阵形成有部分问题，小弟只是想学习学习高手的源代码，代码冗杂请见谅(the code of DC—powerflow caculation by FX provide 7 kind of controll mode，but there are some problems in the formation of Y matrix.please let me download some code by good operator )

TDMS的文件读取到Matlab。 优点： -支持读取v2的文件 -不需要使用NI的DLL，因此它不需要32位窗口 - 支持隔行扫描数据 -只允许读的名称及属性，以得到一个文件是什么感觉快 - 允许读数据的特定子集 (Reads TDMS files into Matlab. Advantages: - supports reading v2 files - doesn t require the NI DLL, thus it doesn t require 32bit windows - supports interleaved data - allows only reading names & properties to get a quick feel for what is in the file - allows reading specific subsets of the data)

BALLBEAM demonsrates Proportional-Derivative (PD) control as applied to a ball and beam simulation experiment. Execute by calling with no arguments. P and PD controllers are implemented which manipulates the beam angle in response to the position of the ball on the beam. The setpoint is indicated by the red marker and adjusted using the slider at the bottom of the figure. The control gain, Kc, and the Derivative Time constant, Td, are adjusted by a sliders located in the right hand control panel. Simulation data is stored in ballbeam.mat for subsequent analysis and parameter estimation. This demo was originally developed with Matlab 5.3 and Matlab 6.0. Some of the user interface code was shamelessly ripped out of the standard Matlab demos. The demo is now updated for Matlab 2010b with additional documentation and suggested exercises for classroom use.

宽带时延波束形成例程，滤波求和方式实现宽带波束形成(design 1d filter-and-sum wideband beamformer with optimization )

多元线性回归算法，能将多个线性的物质之间的变量和自变量之间建立相关度高的线性回归方程。(Multiple linear regression algorithm, can the variables and between multiple linear material to set up linear regression equation with high correlation between independent variables. )

PCDMIS电极检测方案,可以自动搜寻基准12个点的位置，并计算出电极坐标(PCDMIS electrode detection scheme that can automatically search for the location of the base 12 points and calculate the coordinates of the electrodes)

This function computes the RMS feature of the signals in x,which are stored in columns. The signals in x are divided into multiple windows of size winsize and the windows are space wininc apart. Inputs x: columns of signals winsize: window size (length of x) wininc: spacing of the windows (winsize) datawin: window for data (e.g. Hamming, default rectangular) must have dimensions of (winsize,1) dispstatus:zero for no waitbar (default) Outputs feat: RMS value in a 2 dimensional matrix dim1 window dim2 feature (col i is the features for the signal in column i of x)

一种流形学习算法（很好用），解耦，恢复原信号，小波包分析提取振动信号中的特征频率。( A fluid manifold learning algorithm (good use), Decoupling, restore the original signal, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  对一个16元等距线阵，间距为半个波长，空间5个相互独立信源从不 同方向入射，信噪比分别为30、25、20、15、5dB。采用MUSIC方法估 计其空间入射方向(For a 16 element equidistant linear array, the spacing is half a wavelength, and five independent sources are incident from different directions. The SNR is 30, 25, 20, 15 and 5dB respectively. Music method is used to estimate the spatial incident direction)
