We check numerically the accuracy of our proposal and conjecture a formula for the asymptotic behavior of principal submatrices of a Toeplitz matrix. info:eu-repo/grantAgreement/ES/DGA/E24-2 info:eu-repo/grantAgreement/ES/FPI/C070-2014 info:eu-repo/grantAgreement/ES/MINECO/FPA2012-35453 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.808 2014 OPTICS 16 / 86 = 0.186 2014 Q1 T1 PHYSICS, ATOMIC, MOLECULAR & CHEMICAL 9 / 34 = 0.265 2014 Q2 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-7715-4970 Esteve, J.G.
