The condition number of matrix $ \textbf {Y}_{a}$ is $ \kappa(\textbf{Y}_{a})$ and $ \lambda_{max}(\textbf{Y}_{a})$ and $ \lambda_{min}(\textbf{Y}_{a})$ are the maximum and minimum eigenvalues, respectively. $ S_{min}$ denotes a threshold value which determines whether or not matrix $ \textbf {Y}_{a}$ is nearly singular. An extension of the equations to include more ports is performed by simply adding additional rows and columns to the matrixes.
