读取图片，提取图片的颜色矩特征，其中变量I=imread( 1.jpg )，1.jpg即为需要读取的图片。(Read the image, color moments extracted image features, including variable I = imread (' 1. Jpg ' ), 1.jpg shall be required to read the pictures.)

分别利用一维logistic、三维lorenz混沌映射实现任意尺寸彩色图像加密与解密（像素值及其位置都发生了改变）。密钥为混沌序列初始值。（内有详细说明）(Respectively, using one-dimensional logistic, three-dimensional lorenz chaotic mapping to achieve any size color image encryption and decryption (pixel values ​ ​ and their positions are changed). Key to the initial value of the chaotic sequence. (With detailed instructions))

说明：  编写定步长复化Simpson公式与变步长（自适应）复化Simpson公式的通用程序，并用变步长（自适应）复化Simpson公式计算π的近似值.(Complex Simpson formula)

说明：  这是一个可以实现ARIMA的预测程序，程序有标注，好理解。(This is a prediction program that can realize Arima. The program is labeled and easy to understand.)

Its a useful book for aptitude and also technical aptitude.

说明：  质子交换膜燃料电池系统的建模与仿真，采用Matlab中simulink进行模块搭建(Simulation of PEMFC)

this code simulates a 4fuzzy PID cotroller for ball-baem system and 3 other systems.

通过matlab编写代码演奏的卡农，用的基准音，没有加入波形修饰所以音色比较单一(matlab matlab playing playing Khanom Khanom Khanom matlab played)

说明：  HFSS在MATALAB中的应用，很好的应用教材(HFSS 3D modeling applications in Matlab)

这是一个matlab代码包，里面包括一百多个数学问题的求解方法，非常实用(this package of matlab code contains more than 100 mathematical problem s solutions)
