| Abstract: | A class of spectrally arbitrary sign patterns with 2n nonzero entries is studied. The sign pattern is proved to be spectrally arbitrary by using nilpotent-Jacobian method, and the given sign pattern is minimally spectrally arbitrary. |
| Keywords: | Nilpotent-Jacobian method nilpotent matrix sign pattern matrix spectrally arbitrary pattern |
