Practical FIR Filter Design in MATLAB Revision 1.1 Ricardo A. Losada The MathWorks, Inc. 3 Apple Hill Dr. Natick, MA 01760, USA January 12, 2004

this is matlab code for ICA

包好一个AP算法matlab程序，以及最早提出AP算法的经典文章及相应PPT(Affinity Propagation algorithm matlab Clustering by Passing Messages Between Data Points.pdf )

说明：  已知n个自变量锁对应的函数值，可用该代码求出Lagrange唯一一个n阶差值多项式。(N independent variables are known to lock the corresponding function value, the code can be obtained only n-order differential Lagrange polynomial.)

基于MATLAB的地震正演模型实现,很适合初学者学习掌握(MATLAB-based seismic forward model implementation, it is suitable for beginners to learn to master)

1.采用遗传算法对男女生样本数据中的身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征进行特征选择，并基于所得到的最佳特征采用SVM设计男女生分类器，并计算模型预测性能（包含SE,SP,ACC和AUC ）。要求自行编写代码实现遗传算法。(1. using genetic algorithm based on the sample data of male and female students in height, weight, love mathematics, love literature, love sports, love pattern recognition feature selection for a total of 6 characteristics, and based on the best features obtained by SVM design and classifier, and the computing model prediction performance (including SE, SP, ACC and AUC). Self coding is required to implement genetic algorithms.)

Smooths a matrix (with/without NaN s) via recursive moving average method and eliminates data gaps. (MOVING_AVERAGE(X,F) smooths the vector data X with a boxcar window of size 2F+1, i.e., by means of averaging each element with the F elements at his right and the F elements at his left. The extreme elements are also averaged but with less data, obviously. Leaving the edges intact. The method is really fast. MOVING_AVERAGE2(X,M,N) smooths the matrix X with a boxcar window of size (2M+1)x(2N+1), i.e., by means of averaging each element with its surrounding elements that fits in the mentioned box centered on it. This one is also really fast. The elements at the edges are averaged too, but the corners are left intact. NANMOVING_AVERAGE(X,F) or NANMOVING_AVERAGE(X,F,1) accept NaN s elements in the vector X the latter interpolates also those NaN s elements surrounded by numeric elements. NANMOVING_AVERAGE2(X,M,N) or NANMOVING_AVERAGE2(X,M,N,1) accept elements NaN s in the matrix X the latter interpolates also those NaN elements surrounded by numeric elements.)

进行快速傅里叶变换的程序，可以利用C++或者MATLAB直接完成快速傅里叶变换(Fast Fourier transform for the program can be utilized C++ or MATLAB directly to complete the fast Fourier transform)

结构动力学逐步法程序，包括wilson theta和常平均加速度法。(Structural dynamics step-by-step procedure, including Wilson, theta and constant mean acceleration method.)
