这是一个单摆模型的分岔行为的分岔图，是我珍藏的，供大家参考。 (This is a simple pendulum model of the bifurcation behavior of the bifurcation diagram, is my collection, for your reference.)

this is EZW algorithm for matlab

In this program we calculate the scattering field of a infinite rectangular surface. I use Physical Optic method and compare the result with exact solution.

说明：  灰度共生矩阵方法用来提供一幅图像的灰度共生矩阵值，然后送到分类器中进行分类(gray level co-occurrence matrix，a very important method of extracting features)

用matlab实现万年编程，显示年月日当前时间(Years to achieve with matlab programming, displays the current month, day time)

BeanSearch for AI. Init a random vector and calculate your behavior.

JPEG连续色调静止图像无损压缩的最新标准JPEG LS的C语言实现，还带有一个很友好的图形用户界面，那些学习图像编码的工程师可以参考一下这个实现的源代码。(JPEG continuous tone still images of the latest standard lossless compression JPEG LS realize the C language, but also with a very friendly graphical user interface, those who study and image coding engineers can refer to this realization of the source code.)

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )
