借助于 MATL AB语言强大的矩阵变换与运算功能 ,利用混合节点法编制含有理想电压源和受控源的大规模电路稳态分析程序。程序具有通用自由的输入格式和直观形象的输出形式 ,为大规模线性电路稳态分析提供了一个便利且有效的辅助工具。文章介绍了程序总体框图和编程要点 ,最后给出应用实例 ,经分析得到各节点电压和各支路电流 。

In virtue of the MATLAB powerful matrix transform and matrix calculation function, a steady-state analysis program for large-scale circuit which contained ideal voltage source and controlled source is composed by mixed-node method. The program is characteristic of general free input format' and output form with intuition and visualization, offers a convenient and efficient tool for large-scale linear circuits steady-state analysis. First the program flow chart and the programming keys are set forth, last application instances are presented. The conclusions of the analysis have corresponding vector diagram and time-domain wave shape, besides every node-voltage and every branch-current.
