一些实用的MATLAB源程序，包括滤波、边缘检测等等(These MATLAB functions were created for the book Digital Image Processing Using MATLAB (DIPUM), by R.C. Gonzalez, R.E. Woods, and S.L. Eddins, Prentice Hall, 2004, ISBN 0130085197. The functions supplement and extend the image processing functionality of MATLAB and the Image Processing Toolbox, both offered by The MathWorks. )

设采样频率为1Hz，对于淹没在复高斯白噪声中的信噪比为 的两个复LFM信号，采用子带带宽为0.1Hz的升余弦滤波器，共9个子带滤波器构成的滤波器组，时间窗为窗长为256的矩形窗，进行仿真(based sampling frequency of 1Hz. For drowned in the complex Gaussian white noise to the signal-to-noise ratio of 2 Minute LFM, using sub-band bandwidth of 0.1 Hz or cosine filter, a total of nine sub-band filter a filter group, time window to window to 256 long rectangular window simulation)

提供了外文文献具体解释了HHT得缺陷之一，模态混叠现象。 通过matlab的仿真具体解释了HHT用于信号分析时出现模态混叠的临界点。(english papers to explain one of the limitations of HHT-MODE MIXING simulation base on MATLAB provide graph to improve that limitation)

系统介绍matlab中添加工具箱的方法（如何添加、添加失败的原因，调用失败的原因）(introduce how to add new toolbox to matlab)

这个演示代码解决双目标函数优化问题，用蝙蝠算法和加权求和法。该程序可以扩展到解决多目标。(This demo code solves bi-objective function optimization problems using the Bat Algorithm and the weighted sum method. The program can be extended to solve any multiple objectives.)
