WebIn 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: [].Any matrix of the form = [()] is a Toeplitz matrix.If the , element of is denoted , then we have , = +, + =. A Toeplitz matrix is not necessarily square.
