WebApr 5, 2024 · I have a 2D-convolution problem, where i need to create a matrix, that is a block toeplitz matrix. WebIn this paper, we consider the approximation of dense block Toeplitz-plus-Hankel matrices by sums of Kronecker products of Toeplitz-plus-Hankel matrices. We present an algorithm for efficiently computing the matrix approximation that requires the factorization of matrices of much smaller dimension than that of the original.
