SOLVING APPARATUS FOR NUMERICAL SOLVING AN INITIAL VALUE DIFFERENTIAL EQUATION, METHOD THEREOF, AND RECORDING MEDIUM STORING A PROGRAM FOR PERFORMING THE METHOD

摘要

PURPOSE: computing device carries out the ODE initial value of numerical value calculating, numerical calculation method comprising the calculation method of program recorded medium, it is non-linear to solve to increase the index error limit, and but reduce the cost with rigidity. ;CONSTITUTION: input unit (110) receives an ODE, initially, calculates time interval and error limitation. Unit (120), which plurally executes, calculates ODE in calculating time interval, and corrects for mistake and use the phase for the error being previously calculated. Calculating, there is the first operation expression to be calculated. The value addition hindered phenol ODE of first operation expression includes the error of previous calculating phase, is worth to Euler approximation. Second operation expression corrects the pervious calculating phase of currently used mistake of error. ;The 2013 of copyright KIPO submissions;[Reference numerals] (110) input unit; (120) accounting unit
