改程序基于改进节点法（Modified Nodal Approach）与全矩阵技术在Matlab中实现线性电阻电路的符号分析。可以在GUI中描述待分析的电路结构、启动分析并直观的观察分析结果。在实现分析功能的同时，提供完整的编辑、输入保护以及数据保存功能。详细说明请见压缩包内文档。-Changed procedures to improve the node-based method (Modified Nodal Approach) with the full-matrix technology in Matlab to achieve linear resistance analysis of circuit symbols. GUI can be described in the circuit structure to be analyzed, start analysis and visual observation of the results of the analysis. Analysis function in the realization at the same time, provide a complete editing, input protection and data retention functionality.
