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.)

Toeplitz-pretreatment-algorithm
在DOA估计中,实际测量和理论肯定存在误差,比如通道误差,阵元位置误差,我们提出一种toplitz的预校正方法。(In the DOA estimate, the actual measurement and theory certainly exist errors, such as channel error, array (position errors, we put forward a kind of toplitz or calibration methods.
