最常用的函数matlab编写程序，比较实用经典，再各个领域都有比较常见的调用(The most commonly used functions matlab programming, more practical classic, then all areas of the more common calls)

本程序可计算主应力大小和方向。主应力就是两个垂直方向的作用力的合力所产生的力在单位截面上的力。(This program can calculate principal stress size and direction. Two vertical principal stress is the force by the force of the force in the direction of force on cross section in the unit.)

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))
