In numerical analysis, the Cash–Karp method is a method for solving ordinary differential equations (ODEs). It was proposed by Professor Jeff R. Cash 〔(Jeff R. Cash, Professor of Numerical Analysis, Imperial College London )〕 from Imperial College London and Alan H. Karp from IBM Scientific Center. The method is a member of the Runge–Kutta family of ODE solvers. More specifically, it uses six function evaluations to calculate fourth- and fifth-order accurate solutions. The difference between these solutions is then taken to be the error of the (fourth order) solution. This error estimate is very convenient for adaptive stepsize integration algorithms. Other similar integration methods are Fehlberg (RKF) and Dormand–Prince (RKDP). The Butcher tableau is: The first row of ''b'' coefficients gives the fifth-order accurate solution, and the second row gives the fourth order solution. == See also == * Adaptive Runge-Kutta methods * List of Runge-Kutta methods 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cash–Karp method」の詳細全文を読む スポンサード リンク
