复化五点数值求积公式的外推算法

Extrapolation Method for Composite Cotes Numerical Integral Formulas

通过Richarderson外推的方法,对复化五点数值求积公式外推,得到高精度的数值积分公式———复化五点求积序列{Ck（h）},数值解的精度大大提高。

Composite cotes integral formula is extrapolated by Richardson extrapolation method,and high precision numerical integral formula——sequence {Ck（h）} of composite cotes integral formulas are obtained.The precision of numerical integral formula is improved.
