Numerical Value Calculation and Analysis of Negative Resistance Oscillator Circuit

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