It is shown that the inverse of a symmetric Toeplitz matrix is determined by at most two of its columns, when properly chosen. A formula for the inverse matrix is given in terms of these columns, generalizing the version of the Gohberg–Semencul formula for the symmetric case. Similar results for the Hermitian case are also given.

In linear algebra, a Toeplitz matrix or diagonal-constant matrix, named after Otto Toeplitz, is a matrix in which each descending diagonal from left to right is constant. For instance, the following matrix is a Toeplitz matrix: Zobacz więcej A matrix equation of the form $${\displaystyle Ax=b}$$ is called a Toeplitz system if A is a Toeplitz matrix. If A is an n × n Toeplitz matrix, then the system has only 2n − 1 unique values, … Zobacz więcej • Bareiss, E. H.
