WebbIn mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, into a collection of smaller … Webb1 okt. 2003 · Here C is a circulant matrix and S is a skew-circulant matrix. In this paper, we propose an iterative Toeplitz solvers for non-Hermitian Toeplitz systems based on the circulant/skew-circulant splitting iteration, or briefly, the CSCS iteration, and it is as follows. The CSCS iteration method: Given an initial guess x(0).
