说明：  利用MATLAB实现基于fft的低通滤波器(the fiter using fft by MATLAB)

说明：  这是我学生利用Lattice Boltzmann method 做的三个工作,可以用来模拟多孔介质渗流问题(This is my students to use the Lattice Boltzmann method to do the three work, can be used to simulate the problem in Porous Media)

Using C + + language and TeeChart control to draw dynamic curve and realize real-time curve 用C++语言和TEECTAL控件绘制动态曲线实现实时曲线(Using C + + language and TeeChart control to draw dynamic curve and realize real-time curve)

根据二值化裂纹轨迹图像，提取裂纹尖端位置(The crack tip position is extracted from the two valued crack trajectory image.)

说明：  计算EEG数据集的锁相值（PLV）。 ％ ％输入参数： eegData是3D矩阵numChannels x numTimePoints x numTrials srate是EEG数据的采样率filtSpec是用于在期望的感兴趣频带中过滤EEG信号的滤波器规范。 它是一个具有两个字段的结构，顺序和范围。 范围指定频带的限制，例如，对于伽马频带，使用filtSpec.range = [35 45]。 在filtSpec.order中指定FIR滤波器的顺序。 一个有用的经验法则可以包括约4到5个周期的所需信号。 例如，对于以500Hz采样的eeg数据，filtSpec.order = 50对应于100ms并且包含~4个周期的γ波段（40Hz）。(Computes the Phase Locking Value (PLV) for an EEG dataset. % % Input parameters: % eegData is a 3D matrix numChannels x numTimePoints x numTrials % srate is the sampling rate of the EEG data % filtSpec is the filter specification to filter the EEG signal in the % desired frequency band of interest. It is a structure with two % fields, order and range. % Range specifies the limits of the frequency % band, for example, put filtSpec.range = [35 45] for gamma band. % Specify the order of the FIR filter in filtSpec.order. A useful % rule of thumb can be to include about 4 to 5 cycles of the desired % signal. For example, filtSpec.order = 50 for eeg data sampled at % 500 Hz corresponds to 100 ms and contains ~4 cycles of gamma band % (40 Hz).)

说明：  ABAQUS的子程序TSAI_WU失效准则(The failure criterion of the subroutine Tsai Wu of ABAQUS)

说明：  % Input: XY(n,2) is the array of coordinates of n points x(i)=XY(i,1), y(i)=XY(i,2) % % Output: Par = [a b R] is the fitting circle: % center (a,b) and radius R % % Note: this fit does not use built-in matrix functions (except "mean"), % so it can be easily programmed in any programming language
