Keywords:
Quadrant interlocking factorization, WZ factorization, Z-matrix, Hourglass matrix, Square matrixAbstract
This paper presents some unaddressed issues on establishment of hourglass matrix. An hourglass matrix is a dense square matrix obtained from quadrant interlocking factorization (QIF) of nonsingular matrix. Then, it is shown that every hourglass matrix is invertible and that hourglass matrix (H-matrix) is a subset of Z-matrix.
