说明：  《基于LMI的控制系统设计、分析及MATLAB仿真》书籍对应各章节的程序，有需要的自取(The program of each chapter in the "LMI based control system design, analysis and MATLAB simulation" book .If you need, please take it.)

gui的教程，书中的例子及题目的源码．彼此是对应的(gui of course, the book＇s source code examples and topics. Each other is the corresponding)

本文为 Stephen J.Chapman《MATLAB 编程（第二版） 》英文影印版的中文译本，这本 书对初学者很好的入门教材。之前从网上下载到邢树军兄弟译的 pdf版本(MATLAB-from fresh to expert.MATLAB Programming for Engineers)

用MATLAB实现对图像的去噪，可以通过修改里面的参数达到不同的效果，调用的是MATLAB的小波包实现的。(Using MATLAB to realize the image denoising can be achieved by modifying the parameters inside the different effects, call the MATLAB wavelet packet implementation.)

求取绝对盐度用新海水状态方程来求取这是新的海水状态方程(Absolute salinity water to strike the state equation with the new strike)

用Boost做的多核集成算法，速度很快，精度很高(MKLBoost )

说明：  matlab源码编写的QPSK调制与解调程序，含载波及采样频率(matlab source code written in QPSK modulation and demodulation process, including the carrier and sampling frequency)

东南大学的《结构模态分析及其损伤诊断》，系统地介绍了结构模态信号处理的算法，是模态信号处理编程和学习的必备选择。(" Modal Analysis and Damage Diagnosis" Southeast University, introduced the algorithm modal signal processing, signal processing modal learning programming and necessary choice.)
