摘要
在双梯形算法的基础上,提出了二重数值积分双梯形递推算法,给出了用C++语言编程实现双梯形递推算法的技术要点,通过对同一实例进行不同的计算实验,测试并比较了复化双梯形算法与双梯形递推算法各自运行时占用Pentium150CPU的时间,实验表明:双梯形递推算法是一种快速计算二重积分、节省CPU时间的高效方法。
The article based on double trapezoidal algorithm puts forward double trapezoidal recursive algorithm for two-dimensional numerical integration.The key technology programming using C＋＋ for the recursive algorithm is given.By means of different experiments for the same example,testing time to take Pentium 150M CPU to run double trapezoidal algorithm and time to take Pentium 150M CPU to run Double Trapezoidal recursive algorithm,the result of experimerts indicate that double trapezoidal recursive algorithm for two-dimensional numerical integration is an effective method saving CPU time.
