The generalized conjugate direction method for solving quadratic inverse eigenvalue problems over generalized skew Hamiltonian matrices with a submatrix constraint
In this paper, we consider a class of constrained quadratic inverse eigenvalue Problem 1.1.Then, a generalized conjugate direction method is proposed to obtain the generalized skew Hamiltonian Beanies matrix solutions with a submatrix constraint.In addition, by choosing a special Spring Washer kind of initial matrices, it is shown that the unique l
