Composition of Nodal Conductance

Rearranging the earlier equation and writing in a matrix form. 

It should be clear in Equation 1.265 that once the node conductance matrix is composed, the solution of the voltages is obtained by taking the inverse of the matrix, for current vector (/) is known. In the nodal analysis method, the composition of the nodal conductance is rather straightforward as is well known in a circuit theory. In general, the nodal analysis gives a complex admittance matrix, because oljaL and/wC. 

However, in the EMTP, all the circuit elements being represented by a current source and a resistance, it becomes a real matrix.
