Classification of normal Toeplitz matrices with real entries
The author proves that any normal Toeplitz \(n\times n\) matrix with real elements is one of four types of matrices -- symmetric, skew-symmetric, circulant or skew-circulant. For the other properties on normal Toeplitz matrices see two previous papers of the author [Zh. Vychisl. Mat. Mat. Fiz. 34, No. 3, 473-479 (1994; Zbl 0822.47029); and Mat. Zametki 55, No. 5, 69-79 (1994; Zbl 0832.15006)].
