Rubei, Elena On completions of symmetric and antisymmetric block diagonal partial matrices. (English) Zbl 1283.15081 Linear Algebra Appl. 439, No. 10, 2971-2979 (2013). Summary: A partial matrix is a matrix where only some of the entries are given. We determine the maximum rank of the symmetric completions of a symmetric partial matrix where only the diagonal blocks are given and the minimum rank and the maximum rank of the antisymmetric completions of an antisymmetric partial matrix where only the diagonal blocks are given.
