| Abstract: | The paper uses the estimates of upper bounds in the inverse matrix A^-1 elements of the nonsingular M matrix and the improved disk theorem of matrix, and gives the Hadamard product of M matrix Band A^-1 of the minimum eigenvalue bounds of the new estimator. These estimates are only related to the matrix elements of A and B, and are easy for calculation. |
