branch. The signs of entries in Amatrix take care of the
polarity of the branch voltage. Extending this argument for all branches in the graph, we can
write the following matrix equation that expresses the KVL equations in the network.
v(t) A

(t)(17.3-3)
where v(t) is the b 1 column vector of instantaneous branch voltage variables, v

(t) is the
(n 1) 1 column vector of instantaneous node voltage variables at all nodes with respect
to the reference node and A
T
is the ...
