Abstract: The paper discusses the solutions of inverse problem AX=B for Hermitian-Hamiltonian matrices with a submatrix constraint, the sufficient and necessary conditions under which the problem is solvable are obtained, and the general expression of the solutions is given. Moreover, to an arbitrary given matrix, the relative optimal approximation solution in the solution set is presented.
