摘要
对Romberg求积公式进行了详细分析。讨论了其显式公式,给出了其误差公式。与Newton-Cotes和Gauss求积公式进行了比较分析,得出Romberg求积并不是一个理想的求积公式。
The Romberg formula is analyzed in detail. The obvious form of Romberg＇s quadrature formula is discussed and the error equation is presented. Based on the analysis and comparison between Romberg formula and Newton-Cotes formula and Gauss quadrature formula, Romberg formula is not a perfect quadrature formula.
