Compression properties for large Toeplitz-like matrices

Numerical Algorithms
Toeplitz matrices are abundant in computational mathematics, and there is a rich literature on the development of fast and superfast algorithms for solving linear systems involving such matrices. Any Toeplitz matrix can be transformed into a matrix with off-diagonal blocks that are of low numerical rank.This compressibility is relied upon in practice ...
