Circuit Solver

This is a basic DC circuit solver made in MATLAB. It uses Modified Nodal Analysis (MNA) to solve circuits from a .cir netlist file.

Features

• Supports up to 40 non-ground nodes.
• Supports resistors.
• Supports independent DC voltage sources.
• Supports independent DC current sources.
• Supports voltage controlled current sources (VCCS).
• Supports voltage controlled voltage sources (VCVS).
• Supports current controlled current sources (CCCS).
• Supports current controlled voltage sources (CCVS).
• Supports ideal opamps.
• Accepts 0, gnd, or ground as the ground node.
• Displays node voltages and extra MNA branch currents.
• Returns the result and MNA matrices in a MATLAB structure.

Basic Usage

result = ec25116031('example.cir');

result.A
