通过现有的人口数据结构特点，对其进行拟合分析后进行长短期的预测-Population data through the existing structural features, their post-fitting analysis of the short and long-term prediction

多点灰色预测程序，matlab 源码，真是可用-Multipoint Predication procedures, matlab source code, is really available

运用matlab进行下个点的预测分析,并画出了预测误差示意图 不错的-Use matlab to the next point prediction analysis, and draw the schematic good prediction error

多变量灰色模型(Multivariable Grey Model,MGM)MGM(1,n)是研究复杂灰色系统的典型模型,其形式是n元一阶常微分方程组,是单点GM(1,1)模型在多点情况的扩展。(Multivariable grey model MGM (1, n) is a typical model for studying complex grey system. Its form is n n first order ordinary differential equations. It
