[0167] The supernode voltage vector is a vector formed by each supernode reference node voltage;
[0168] The supernode current vector is a vector composed of the sum of all currents flowing into each supernode;
[0169] The length of the voltage vector of the non-reference node is the number of all non-reference nodes, and its i-th element P i is the potential of non-reference node i to its reference node, which is the sum of the voltages of all ideal voltage source branches on the path from non-reference node i to its reference node;
[0170] The row of the mutual conductance matrix of the super node and the non-reference node corresponds to the super node, the column of the mutual conductance matrix of the super node and the non-reference node corresponds to the non-reference point, and the ith row of the super node and the non-reference node Element P of column j ij is the mutual conductance of supernode i and non-reference point j or the self-conduction of non-reference...
