WebOct 3, 2024 · In the practical computation, the product of a symmetric block Toeplitz matrix (the coefficient matrix) exponential and a vector is involved in the exponential integrator method. Therefore, the shift-invert Lanczos method [ 44, 52] is employed to approximate the symmetric block Toeplitz matrix exponential. WebA Block Toeplitz Matrix with Toeplitz Blocks (BTTB) is the 2 -D analog to a toeplitz matrix: This means that if we consider the blocks as elements, we obtain a toeplitz matrix. …
