| Abstract: | Nonnegative matrices are a kind of special matrices which have extensive applications.In this paper,the authors study a kind of matrix which is connected with nonnegative matrices:N-matrix.Its judging on N-matrix are studied.At last,a method for N-matrix and its algorithm desgin is given.Two examples are given to prove its effectiveness. |
