| Abstract: | Based on several practical circuit examples, the method for application in analyzing dynamic circuit was introduced. The instruction ＂dsolve＂ was used to solve the differential equation or group of differential equations. The instruction ＂diff＂ was used to realize the operation of derivative. If the value of voltage（current） is known, the value of current（voltage） can be obtained. The instruction of ＂plot＂ was used to draw the curve of the variability of voltage and current. The simulation model of the circuit can be established directly with the help of the toolbox simulink, which made the solving process simple and brief. |
