Indefinite matrices of linear electrical circuits, their pseudoinverses, and applications in related fields
Cristian E. Onete, Maria Cristina C. Onete · 2010
This paper presents the group of indefinite matrices of linear circuits in a general context. Specifically, the indefinite modified admittance matrix and its pseudo-inverse are shown for the first time. Closed formulas for their respective pseudo-inverses, and further examples from both electrical and nonelectrical fields are also shown.
