在总结数学建模竞赛历届考题解题模式的前提下,从数据解析、插值与拟合、数据仿真、回归解析等四个层面归纳了数据处理方法与数学软件在数据建模比赛中的运用,能够在数学建模中,为如何选择数据处理模式带来启发。 On the premise of summarizing the mode of problem solving of the previous questions of mathematical modeling contest, this paper summarizes the application of data processing method and mathematical software in data modeling contest from four aspects: data analysis, interpolation and fitting, data simulation and regression analysis. In mathematical modeling, how to choose the data processing mode to bring inspiration.
