In this paper we show that the Drazin inverse of singular Toeplitz matrix can be represented as a sum of products of lower and upper triangular Toeplitz matrices and give the explicit expression, which generalizes the well-known result by Gohberg and Semencul regarding the inverse of Toeplitz matrix.
