Leslie_model
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.)

frequency_extrapolated_method
说明： 中间的程序是外推程序,.........
但是下面的程序仿真部分和外推部分的标号有写出入,因为不是同一时期编的
请大家注意：
程序中用的是频域外推法，在葛德彪的书中有详细的介绍。(Central procedure is the extrapolation procedure ,......... but some of the following procedures for simulation and extrapolation part of the labeling has to write out, because they are not made during the same period the U.S. Please Note: The procedure used is the frequency of extra-territorial extrapolation method, in the GE De-biao book has a detailed introduction.)
