Computational graphs for matrix functions
Elias Jarlebring, Massimiliano Fasi, Emil Ringh
Many numerical methods for evaluating matrix functions can be naturally viewed as computational graphs. Rephrasing these methods as directed acyclic graphs (DAGs) is a particularly…

Linearizability of eigenvector nonlinearities
Rob Claes, Elias Jarlebring, Karl Meerbergen +1
We present a method to linearize, without approximation, a specific class of eigenvalue problems with eigenvector nonlinearities (NEPv), where the nonlinearities are expressed by s…

Infinite GMRES for parameterized linear systems
Elias Jarlebring, Siobhán Correnty
We consider linear parameter-dependent systems for many different , where is large and sparse, and depends nonlinearly on . Solving such systems individua…
