摘　　要：在电路分析中,通常会要求对电路全面求解,例如要求得到全部电流或电压,常用的求解方法有网孔电流法或节点电压法。对于复杂网络,此类方程的手工解算是很困难的。本文以一个正弦交流电路的节点电压求解为例,采用Matlab软件进行数学建模,对方程进行了辅助求解。探讨了利用Matlab软件解算电路的方法,并给出相应结论。Matlab软件在电路求解当中的运用,简化了运算过程。In circuit analysis, it usually required to solute the circuit overall, example： to get all currents and voltages, solving methods are commonly used： mesh current method or the node voltage method. For the complex network, the equation of the manu- al calculation is difficult. Based on the node voltage for a sinusoidal alternating circuit, mathematical modeling was made by using Matlab software, the equation was aided solution. Discussion on the method of solution of the circuit by using Matlab software, and the corresponding results were given. Application of Matlab software in circuit solving, simplified the operation process.
