Robust Parametric Macromodeling Using Multivariate Orthonormal Vector Fitting [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2008 A robust multivariate extension of the orthonormal vector fitting technique is introduced for rational parametric macromodeling of highly dynamic responses in the frequency domain. The technique is applicable to data that is sparse or dense, deterministic or a bit noisy, and grid-based or scattered in the design space.

Vector Fitting for Matrix-valued Rational Approximation [PDF]
SIAM Journal on Scientific Computing, 2015 Vector Fitting (VF) is a popular method of constructing rational approximants that provides a least squares fit to frequency response measurements. In an earlier work, we provided an analysis of VF for scalar-valued rational functions and established a connection with optimal $H_2$ approximation.
