Constrained inverse eigenproblem and associated approximation problem for anti-Hermitian \(R\)-symmetric matrices
The relations between the eigenproblem involving a complex square anti-Hermitian R-symmetric matrix and the corresponding eigenproblems for anti-Hermitian matrices are given. The solutions of constrained inverse eigenproblems and approximation problems are then decomposed into the same kind subproblems for anti-Hermitian matrices in complex field with smaller dimension. Explicit solutions of the subproblems are given.
