BlockDiagonalization

usefull to learn graphs in matlab

常规声波波动方程正演程序，可动画演示,未做边界处理(acoustic equation wave forward modeling based on convention grid)

The following Matlab project contains the source code and Matlab examples used for a pretty seashell gui. This GUI draws a seashell, using a parametric surface. The parameters of the seashell can be modified with sliders and buttons in the GUI. See also the seashell.m file, also on MATLAB Central (with no GUI). The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there

这是一个三次样条插值的.m程序 输入的是一个二维数组A(Nx2) 插值方法为: S(x) = A(J) + B(J)*( x - x(J) ) + C(J)*( x - x(J) )**2 +D(J) * ( x - x(J) )**3 for x(J) <= x < x(J + 1) (This is a cubic spline interpolation. M program input is a two-dimensional array A (Nx2) interpolation method: S (x) = A (J)+ B (J)* (x- x (J ))+ C (J)* (x- x (J))** 2+ D (J)* (x- x (J))** 3 for x (J) )

说明：  非常好用的程序，里面包括EMD分解和HHT谱分析的程序，可以很好地处理非线性数据(Very useful procedure, which include EMD and HHT spectrum decomposition process, can well handle nonlinear data)

几个控制理论的小程序，可以方便学习自动控制理论这门课(Can easily end the camera to the image transmitted matlab program for the software called.)

经典的OFDM仿真程序,比较简单，适合初做仿真者用。(A symple program of OFDM)

解耦，恢复原信号，有小波分析的盲信号处理，包含了阵列信号处理的常见算法，仿真图是速度、距离、幅度三维图像，利用自然梯度算法，最小均方误差（MMSE）的算法，多抽样率信号处理。(Decoupling, restore the original signal, There Wavelet Analysis Blind Signal Processing, Contains a common array signal processing algorithm, FIG simulation speed, distance, amplitude three-dimensional image, Use of natural gradient algorithm, Minimum mean square error (MMSE) algorithm, Multirate signal processing.)

说明：  三相逆变器SIMULINK仿真，可以用来完成相关仿真实验(Simulink simulation of three-phase inverter)

该内容是关于fdtd的源码,我用过,ok!不错!()
