Description
Summary:Najafi et al. (Appl Math Lett 33:1–5, 2014 ) have elaborated an approach to compute the inverse of arrowhead matrices. This paper concerns with offering an alternative simple and neat framework to obtain an explicit formula for the inverse of arrowhead matrices. More precisely, the adopted manner makes us capable to derive the inverse of block arrowhead matrices. In addition, we propound a strategy to reckon the inverse of doubly arrow matrices. Finally illustrative examples are examined which reveal the applicability and feasibly of the handled strategies.
