Short recurrence relations for rational Krylov and orthogonal rational functions inspired by modified moments KU Leuven
In the MOMENTUM project research teams in Leuven and Lille (France) will study short recurrences for rational Krylov and orthogonal rational functions inspired by studying modified moments matrices. This will lead to new theory and algorithms for computing short recurrences. The theoretical envisaged enrichment is a thorough analysis of the displacement structure of the associated modified Gramians providing new (coupled) recurrences of the ...
