Expansion of fill function on Auto CAD AUTOCAD填充功能的增强
A series of heavy calculation work can be done easily by EXCEL's auto fill option when ODEs are treated with Euler's method or Runge Kutta method, and high precision numerical solutions of ODEs can be obtained by EXCEL. 在EXCEL的界面下,欧拉折线法或龙格-库塔法的一系列繁杂计算可以简单地通过对EXCEL单元格的自动填充来实现,所得到的数值解具有很高的精度。
