摘要
数值积分是计算方法或数值分析理论中非常重要的内容,数值积分方法也是解决实际计算问题的重要方法。本文对几种常用的数值积分方法进行了简要的分析,并用这几种方法对被积函数是普通函数做了数值积分,龙贝格(Romberg)积分方法效果较好。
Numerical integration is an very important content of calculation method and numerical analysis, and the numerical integration method is also an important method to solve practical calculation problems. Some commonly used numerical integration methods were analyzed, and some examples were given at the cases that the integrands were normal functions by using these numerical integration methods. The results achieved by Romberg method were better.
