matlab的有限元计算代码，可计算梁、桁架等结构(matlab，FEM)

Euler method finite difference

粒子滤波程序，简单易懂，初学者一定要看，最基本的算法(Particle filter, easy to understand, beginners must look)

对连续时域信号进行采样处理成为离散信号。完成信号绘图并显示其采样图像(signal sampling)

学习matlab的好资料,是你学习的好助手，你可以用来学习matlab和数学建模(this is a learn matlab very good )

This folder contains Matlab functions for the Enhanced Interval Approach (EIA) in: Simon Coupland, J. M. Mendel and Dongrui Wu, “Enhanced Interval Approach for Encoding Words into Interval Type-2 Fuzzy Sets and Convergence of the Word FOUs,” IEEE World Congress on Computational Intelligence, Barcelona, Spain, July 2010. All following functions were tested in Matlab 7.4.0 (R2007a) under Windows 7: centroidIT2: Compute the centroid of an IT2 FS. EKM: Implement the Enhanced KM algorithms. IA: Implement the Interval Approach for word encoding. mainJPL: Illustrate IA and EIA using the JPL dataset. mainWeb: Illustrate IA and EIA using the Web dataset. mg: Compute the membership grades of a vector of numbers on a T1 FS. plotFigures: Plot Figs. 3.18, 3.19 and 3.20 in the book. plotIT2: Plot an IT2 FS.

滤波器阶数固定时,代价函数和信噪比之间的关系 信噪比固定时,代价函数和滤波器长度之间的关系(order filter fixed, cost function and the relationship between the signal-to-noise ratio signal-to-noise ratio fixed, Filters cost function and the relationship between length)

经验模态分解（EMD），对imf进行分析，再采用类小波阈值去噪。(Empirical Mode Decomposition (EMD), were analyzed for the imf, then using class wavelet thresholding.)
