The first author and F. J. Hall defined recently a G-matrix as a real nonsingular matrix having the property that the transpose if its inverse can be written as a multiple of the original matrix by nonsingular diagonal matrices from both sides. The class of G-matrices was shown to possess interesting properties. In this paper, some new characterizations are found and extensions to rectangular and complex matrices are discussed.
