摘要
The stability of interval matrices has recently been studied and many results have been obtained. Consider n×n-dimensional real matrices P= (p<sub>ij</sub>) and Q=(q<sub>ij</sub>), which satisfy p<sub>ij</sub>≤<sub>q</sub><sub>ij</sub> and denote N[P, Q]={A=(a<sub>ij</sub>)∈R<sup>n×n</sup>|p<sub>ij</sub>≤a<sub>ij</sub>≤q<sub>ij</sub>, i, j=1, 2,…, n,} the interval matrix N[P, Q] is said to be stable if A is stable (i. e.
