Revisiting IRKA: Connections with pole placement and backward stability
C. Beattie, Z. Drmac, S. Gugercin
The iterative rational Krylov algorithm (\textsf{IRKA}) is a popular approach for producing locally optimal reduced-order -approximations to linear time-invariant (L…
New robust ScaLAPACK routine for computing the QR factorization with column pivoting
Zvonimir Bujanović, Zlatko Drmač
In this note we describe two modifications of the ScaLAPACK subroutines PxGEQPF for computing the QR factorization with the Businger-Golub column pivoting. First, we resolve a subt…
Learning low-dimensional dynamical-system models from noisy frequency-response data with Loewner rational interpolation
Zlatko Drmač, Benjamin Peherstorfer
Loewner rational interpolation provides a versatile tool to learn low-dimensional dynamical-system models from frequency-response measurements. This work investigates the robustnes…
An algorithm for the complete solution of the quartic eigenvalue problem
Zlatko Drmač, Ivana Šain Glibić
Quartic eigenvalue problem naturally arises e.g. when solving the Orr-Sommerfeld equation in the analysis of the stability of the {P…
