WebNote. The four properties in the definition of pseudoinverse are called the Penrose equations. Roger Penrose in 1955 showed that every finite matrix (with real or com-plex entries; in the complex case, symmetry is replaced with conjugate symmetry) has a unique pseudoinverse satisfying the four equations (R. Penrose, “A General- WebWe study numerical approaches to computation of spectral properties of composition operators. We provide a characterization of Koopman Modes in Banach spaces using Generalized Laplace Analysis.
