說明：??Leslie模型實例：基于Leslie矩陣的算法，同時將人口按10年一組分成m個年齡段，并根據一些影響人口數量和結構的重要因素(建立模型。再根據我國近十年的二孩出生率的實際情況并結合少數民族不受影響的因素，通過Matlab畫出擬合曲線對2017-2030年我國每年人口總數做出預測。此后，根據近十年0-14歲、15-64 歲、65歲及以上三個年齡段的人數，計算出人口撫養比，用Matlab預測至2030年的人口結構。為了使預測更加精確，我們還將夫婦的生育意愿考慮到模型當中。

(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.)
