摘要：
The first author and Hall defined recently a G-matrix as a real non-singular matrix A such that there exist diagonal matrices D-1 and D-2 for which (A(T))(-1) = D(1)AD(2). 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.
