摘　　要：通过几个具体的电路实例,介绍了MATLAB的电路分析方法在动态电路分析方面的应用.利用MATLAB的dsolve函数来求解电路的微分方程(组);用diff函数求导数,根据电压(电流)求出电流(电压);利用plot函数绘制电压和电流的变化曲线;利用Simulink功能可直接建立电路仿真模型,使解题过程变得简单、便捷.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.
