在写SSI算法的时候，因为要画稳定图，所以牵涉到了双坐标轴的使用问题。查看Matlab的Help文件，对双坐标轴函数（plotyy）的表述不是很详细，或者是我没有读太懂吧。 下面对plotyy函数的使用做一个详细的学习,SSI algorithm in the time to write because of the need to draw a stable map, so involved the use of dual-axis problem. See Matlab s Help

这是一个关于matlab的概率实验函数，里面包含了多种实验-This is a probability function on matlab s experiment, which contains a variety of experimental

能够用MATLAB实现DES算法加密，包含密钥生成和S盒的生成函数(DES algorithm can be encrypted with MATLAB, including key generation and S-box generation function.)

SM4加密算法的matlab语言实现，采用s盒变换、轮函数等。(SM4 encryption algorithm is realized by MATLAB language, using S-box transformation, wheel function and so on.)
