Abstract: Let $TH_n$ be the space of $(T+H)$-matrices of order $n$. The paper considers the following question: Which unitary matrices $U$ satisfy the condition $\forall A\in TH_n\to U^*AU\in TH_n$? A criterion for verifying whether a given matrix $U$ has this property is proposed.
Key words and phrases: unitary similarity, $(T+H)$-matrices, centrosymmetric matrices, tridiagonal matrices.
