• Generalized centrosymmetric matrix
• Spectra constraint
• Perturbation theory
• Sparse structure

It establishes a perturbation bound of a generalized centrosymmetric model updating problem with spectra constraints. A method is presented to preserve the sparsity of the model. The numerical examples show that the method is feasible and effective.
