From this page, you may download the software that implements the matrix arithmetic of Quasi-Toeplitz matrices associated with a symmetric symbol introduced in the paper “On certain matrix algebras related to quasi-Toeplitz matrices”, by D.A. Bini and B. Meini. The software, which can be downloaded from this link, also contains the scripts test1 and test2 that generate the data in Table 1 and Table 2 of the paper, respectively. Since part of the code is randomized, namely the part related to the compression of the compact correction in the CQT representation, the output of the tests may vary slightly in different runs of the code.
