From: Reduced-order modelling of parametric systems via interpolation of heterogeneous surrogates
Interpolation of Loewner ROMs built with individual bases. The nonparametric Loewner ROMs are built in the compressed form with different frequency shift s and they are interpolated matrix-wise directly using (46). The FRFs at \(p_* =65.51\) are shown in the figure
