| Abstract: | The exact expressions of the inverses of tridiagonal matrices are established in this note. Also, it is obtained the compressed expressions of high determinants, and some propertices of ergen values of these matrices, when they are nonnegative p-matrices, they can be orthogonally similar to inverse-nonnegative's. |
