A matrix is said to have the Perron-Frobenius propertyif its spectral radius is an eigenvalue with a corresponding nonnegative eigenvector. Matrices having this and similar properties are studied in this paper as generalizations of nonnegative matrices. Sets consisting of such gener- alized nonnegative matrices are studied and certain topological aspects such as connectedness and closure are proved. Similaritytransformations leaving such sets invariant are completelydescribed, and it is shown that a nonnilpotent matrix eventuallycapturing the Perron-Frobenius propertyis in fact a matrix that alreadyhas it.
