Runge-Kutta-Fehlberg方法在负阻振荡电路求解中的应用(英文)

The Application of Runge-Kutta-Fehlberg Method in Solving Negative Resistance Oscillator Circuit

结合负阻振荡电路,采用五阶Runge-Kutta-Fehlberg方法分别用C语言程序和MATLAB进行求解,均得出了正确的结果,同时介绍了用MATLAB对C程序计算结果的调用.经比较,两种方法各有所长.在图形显示方面。

By using both language C and MATLAB,this article introduced the five-order Runge-Kutta-Fehlberg method＇s application in solving a negative resistance oscillator circuit.Both of the two methods had gotten correct results.Simultaneously,the method how to transfer the results which were calculated by language C program to MATLAB was introduced.After comparing,it was concluded that both of the two ways had their strong points,but MATLAB had more advantages in displaying figures.
