Abstract
Given four complex matrices A, B, C and D where A ? Cn?n and D ? Cm?m and
given two distinct arbitrary complex numbers ?1 and ?2, so that they are not
eigenvalues of the matrix A, we find a nearest matrix from the set of
matrices X ? Cm?m to matrix D (with respect to spectral norm) such that
the matrix A B C X ! has two prescribed eigenvalues ?1 and ?2.
