When analyzing complex networks, an important task is the identification of those nodes which play a leading role for the overall communicability of the network. In the context of modifying network…
The computation of , the action of a matrix function on a vector, is a task arising in many areas of scientific computing. In many applications, the matrix is sparse but so large that only a …
The computation of matrix functions f(A), or related quantities like their trace, is an important but challenging task, in particular, for large and sparse matrices A. In recent years, probing meth…
Given a limited amount of memory and a target accuracy, we propose and compare several polynomial Krylov methods for the approximation of $f(A){b}$, the action of a Stieltjes matrix function of a l…
