shannon编码，其中讲了一些香农编码的步骤，而且有shannon编码的程序(shannon encoding, which made some of the steps Shannon coding, and coding procedures shannon)

此文件含有大量程序，是《先进 PID 控制及其 MATLAB 仿真 （程序）》书里的程序，含教材。(This file contains a lot of procedures, are " advanced PID control and MATLAB simulation (program)" book of procedures, including teaching materials.)

matlab中的Zig_Zag扫描程序，需要的朋友可以看看。。。。(matlab in Zig_Zag scanning procedures, the needs of our friends can see. . . .)

polar码的SC译码算法，可设置不同信噪比，不同码长，可改为SCL算法和CA_SCL算法。核心部分采用C程序编写，主要框架采用matlab编写，极大提高了运行速度。 (SC polar code decoding algorithm, you can set different SNR, different code lengths, can be changed SCL algorithm and CA_SCL algorithms. The core part of C programming, the main framework for the use of matlab prepared, greatly increasing the speed.)

Dana Quade in 1979 proposed a test that is often more powerful than the Friedman test. It also eliminates block differences but weights the raw data indicate possibly more marked treatment effects. Whereas the Friedman test is basically an extension of the sign test, the Quade test is effectively an extension of the Wilcoxon signed rank test and is equivalent to it when the treatments are two.

与模糊数学相关的,模糊聚类分析的有效性问题初探,FCM算法是论文中不可或缺的部分,在此将FCM算法的两种迭代形式的MATLAB代码写于下,也许有的同学会用得着:(Fuzzy clustering analysis and fuzzy validity problems of the mathematically related, FCM algorithm is an integral part of the paper, in the form of the FCM two iterative algorithm MATLAB code written in the next, and perhaps some students will use have a:)

关于MATLAB中S函数的编写指导，内容非常详细。(On the preparation of MATLAB S function guide, the content is very detailed)

说明：  Leslie模型实例：基于Leslie矩阵的算法，同时将人口按10年一组分成m个年龄段，并根据一些影响人口数量和结构的重要因素（建立模型。再根据我国近十年的二孩出生率的实际情况并结合少数民族不受影响的因素，通过Matlab画出拟合曲线对2017-2030年我国每年人口总数做出预测。此后，根据近十年0-14岁、15-64 岁、65岁及以上三个年龄段的人数，计算出人口抚养比，用Matlab预测至2030年的人口结构。为了使预测更加精确，我们还将夫妇的生育意愿考虑到模型当中。(Based on the Leslie matrix algorithm, the population is divided into m age groups according to a group of 10 years, and according to some important factors that affect population size and structure Modeling. Then according to the actual situation of the birth rate of second-born children in China in the past ten years and combining the factors that are not affected by ethnic minorities, drawing a fitting curve through Matlab will make a prediction for the total population of China in 2017-2030. After that, based on the number of people aged 0-14, 15-64, and 65 years of age in the last ten years, calculate the dependency ratio of the population and use Matlab to predict the population structure by 2030. In order to make the prediction more accurate, we also consider the couple's fertility intention in the model.)
