CIRCUIT SIMULATION IN MATLAB

In this paper a circuit simulation of linear electric systems containing independent and dependent sources of DC voltage and/or current is proposed. For circuit simulation is used nodal analysis method and the program based on this method was created in MATLAB environment. The symbolic representation of constraint equations for node voltages and nodal equations for non reference nodes and supernodes is drawn up after setting of prescribed input data and the reference node. Symbolic representation of nodal voltages, branch voltages and branch currents and calculation their numeric values for given circuit element parameters can be also generated.
