Rational kernel-based interpolation for complex-valued frequency response functions

no code implementations25 Jul 2023 Julien Bect, Niklas Georg, Ulrich Römer, Sebastian Schöps

This work is concerned with the kernel-based approximation of a complex-valued function from data, where the frequency response function of a partial differential equation in the frequency domain is of particular interest.
