Abstract:
We initially present the range of the elements of inverse matrix of A for two nonsingular M-matrices A and B. We further obtain a new estimation formula of the lower bound of the minimal eigenvalue of B° A-1 with the theorem of Brauer. Theoretical analysis and numerical examples demonstrate that it improves the existing results.
Key words: lower bound, M-matrix, Hadamard product, inverse matrix
