EMD经验模态分解,用于信号处理，常和hilbert-huang变换一起用于信号特征提取、信号消噪等领域。(EMD EMD for signal processing, often with hilbert-huang transform for signal feature extraction, signal de-noising and other fields.)

说明：  用积分方程法求P波波场，适合初学积分方程研究散射问题(Integral Equation Method P wave field)

this is a FFT algorith using by matlab code

matlab实现4阶龙格库塔的一个示例，分为三个子函数来调用(Matlab 4 order LongGe coulthard s a sample)

说明：  本压缩包内涵丰富，需要自己提取学习修改，其中包括无损检测，信号处，超声波仿真及相关程序，内含有帮助文档和学习文件文献。(This package is rich in content and needs to be extracted, learned and modified by ourselves, including nondestructive testing, signal processing, ultrasonic simulation and related programs, including help documents and learning documents.)

介绍了使用MATLAB实现对Kalman滤波的模拟，对Kalman滤波的学习和使用很有帮助。(Introduced the Kalman filter using MATLAB to realize the simulation, the learning and use of Kalman filtering helpful.)

matlab经典算法的程序-方程解，code of the book(classical algorithm matlab procedures- Equations, code of the book)

MATLAB电机仿真精华50例,源代码，中的一部分源代码(MATLAB simulation of the essence of motor 50 cases, source code, part of the source code)

上一个的继续,连续有九个压缩文件,大家可以打开解压后自己慢慢享用,这个都是本人调试通过了的,希望共同进步!(A continuation of a row has nine compressed file, everyone can open their own after extracting slowly to enjoy, this is my debug adopted, and I hope common progress!)

说明：  杨大成的移动传播环境，包含大尺度衰落信道，小尺度衰落信道的详细表述。还有一些建模方法。(Yang Dacheng mobile communication environment, including large-scale fading, small-scale fading detailed presentation. Some modeling.)
