| 摘 要： | 随着科学技术的进步,探索和建立非线性电路的理论体系并加以应用,已处于十分重要的地位,并具有广阔的应用前景,有较大的理论意义和实用价值.本文结合负阻振荡电路,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.经比较可见,两种方法各有所长.在图形显示方面,Matlab更具优越性.

| Abstract: | Along with the progress of science and technology,exploring and establishing nonlinear circuits' theoretical system and taking it to be used seems very important,which will have a wide application prospect.Thus it will have some theoretical meaning and functional value.By using language C and Matlab,this article introduces the five-order Runge-Kutta-Fehlberg method's application in resolving a negative resistance oscillator circuit,and both of the two methods can get correct results.Simultaneously,it introduces how to transfer the calculated results of C program under Matlab.After comparing,it is concluded that both the two methods have their strong points.Matlab has more advantages in displaying figures. |
