William R. Ferng, Wen-Wei Lin, Daniel J. Pierce, Chern-Shuh Wang · Numerical Linear Algebra with Applications · 2000
In this paper we present some theory for a non-equivalence transformation of matrix eigenvalues for λ-matrix polynomials. Application of this transformation to eigenvalue embedding for model tuning on a realistic industry problem is illustrated. The new approach has several advantages such as flexibility, efficiency, and structure-preservation. A numerical experiment on a pseudosimulation data set from The Boeing Company is reported.
