Symbolic Analysis Implementation for Linear Resistive Circuits Using MATLAB

This program implements symbolic analysis of linear resistive circuits using the Modified Nodal Approach (MNA) combined with full matrix technology in MATLAB. Through the graphical user interface (GUI), users can describe the circuit structure to be analyzed, initiate the analysis process, and visually observe the analytical results, thereby achieving comprehensive circuit analysis. The implementation utilizes matrix operations and symbolic math tools to solve circuit equations symbolically, preserving component parameters as variables rather than numerical values. Beyond the core analysis functionality, the program provides complete editing features, input validation protection to prevent erroneous entries, and data saving capabilities to meet various user requirements. The algorithm employs nodal analysis with additional device equations to handle voltage sources and other elements effectively. For detailed documentation regarding the program's architecture and usage, please refer to the documents included in the accompanying compressed package. We hope this information proves beneficial for your work.
