VIII. CONCLUSION
Node or mesh analysis matrix equations for a circuit are
written directly by inspection of the circuit. Conductance or
resistance component matrices show the usual self and mutual
terms and exhibit diagonal symmetry. The effects of dependent
or independent sources in the circuit enter by inspection
of the circuit as separate terms in the matrix formulation.
Matrix solutions of these general formulations place in evidence
the existence of a return difference matrix. Evaluation
of an arbitrary solution vector using matrix methods with
matrix computer calculation programs is easily done. The
output matrix method is convenient for evaluation of two-port
parameters, ThCvenin or Norton equivalent circuit parameters,
or for determination of state-variable circuit parameters.
With personal computers and matrix analysis programs now
economically reasonable for students, greater emphasis on
matrix analysis methods in the circuit analysis cumculum is
appropriate. Matrix computer circuit analysis, computer circuit
simulation, and normal circuit analysis methods work well
