Serial title, monograph or event: | Special Matrices | Volume: | 7 | Issue: | 1 | Abstract: | We give a necessary and su cient condition for the existence of a quasi-distance matrix where some positive o -diagonal entries have been prescribed. Moreover, we give an algorithm for obtaining such a matrix. We analyze also the case where distances instead of quasi-distances are considered. | URI: | https://hdl.handle.net/10316/107389 | ISSN: | 2300-7451 | DOI: | 10.1515/spma-2019-0016 | Rights: | openAccess |
