| Abstract: |
| By using the upper and lower bounds on the monotone sequence for inverse matrix A-1 elements of nonsingular M matrix A and improved disk theorem of matrix,this paper obtains the new estimator of the minimum eigenvalue bounds decreasing monotonically of Hadamard product of M matrix B and A-1. |
| Key words: matrix Hadamard product minimum eigenvalue lower bound |
