测量稀土元素的光谱的matlab程序,可以作图，十分简单方便(REE spectra measurements matlab program, you can plot is very simple and convenient)

费诺编码matlab程序，含有两个子函数，需要调用！(Fenno coding matlab program, consists of two sub-functions, you need to call!)

说明：  这是一个matlab的直方图均衡程序，先读入一副彩色图像，将其转成灰度图，输出该图的直方图，做均衡以后再次输出，可以看到均衡后图像直方图比较均匀了。(this is a histogram program based on matlab)

程序仿真得图为原信号与u律压扩信号的互补累积函数曲线图。仿真参数：子载波N=128，采用QPSK调制。(The photo shows the original simulation program was u-law signal and the signal of the complementary cumulative function expansion curve. Simulation parameters: sub-carriers N = 128, using QPSK modulation.)

说明：  传染病模型是指传染病的基本数学模型，研究传染病的传播速度、空间范围、传播途径、动力学机理等问题，以指导对传染病的有效的预防和控制。常见的传染病模型按照传染病类型分为SI、SIR、SIRS、SEIR模型等。由于2019年末出现的新冠肺炎有一定的潜伏期，与病人接触过的健康人并不马上患病，而是称为病原体的携带者，归为E类。(infectious disease model simulation)
