数值分析中,龙格-库塔法(Runge-Kutta methods)是用于非线性常微分方程的解的重要的一类隐式或显式迭代法。这些技术由数学家卡尔·龙格和马丁·威尔海姆·库塔于1900年左右发明。Runge-Kutta公式的思路就是利用区间内一些特殊点的一阶导数值的线性组合来替代某点处的n阶导数值,这样就可以仅通过一系列一阶导数值来得...

Runge-Kutta Method MyPhysicsLab – Runge-Kutta Algorithm The Runge-Kutta algorithm is the magic formula behind most of the physics simulations shown on this web site. The Runge-Kutta algorithm lets us solve a differential equation numerically (that is, approximately); it is known to be ...
Runge-Kutta methodComputer calculationsNumerical solutionStorageThree techniques of increasing generality for reducing storage requirements of Runge--Kutta codes are described. Although the first two require the formula to have special properties, they are broadly applicable and may substantially reduce the ...
