A class of bordered diagonal matrices, here called tree-matrices, is investigated. For any such matrix, a similar matrix is found in the class of diagonal matrix modified by a matrix of rank one, and viceversa. A Sturm sequence for the characteristic equation is found for real symmetric tree-matrices. Some of previous results are extended to k-tree matrices and the Woodbury formula is used to find the inverse. In addition, examples are given to be used as test matrices.
