Software-platform of general circuit analysis based on MATLAB GUI

In order to automatically analyzing general circuits, a software system known as "General Circuit Analysis Platform" is developed with Matlab programming in this paper. This system consists of six parts including five general circuit analyzers and one multi-calculator. The fundamental theory with node-listing method used to develop the system is presented. The matrix equation describing the circuit is derived. Four examples are given to respectively demonstrate the stable-state analysis (Fig. 3), frequency analysis (Fig. 5), transient-state analysis (Fig. 7) and common calculation (Fig. 8) of general circuits. The results show that the General Circuit Analysis Platform works properly with both friendly graphic user interface and flexible ways for data input and output.
