Our result is applied to give the closed-form formula of the inverse of the considered matrix. We give the relation between the defined matrix and Helmert matrix which has been used for proving the statistical independence of a number of statistics. Also we find the condition numbers of some matrices for some special values of q.eninfo:eu-repo/semantics/closedAccessFactorization of matricesmatrix inversionq-calculusmatrix norms and conditioningArticle10.1080/03610926.2019.16458542-s2.0-85074436210Q2WOS:000478255600001Q4
