Software related to my research:
- t-frechet: Toolbox for computing t-functions (and their Fréchet derivatives) of third-order tensors (MATLAB)
- sketched_fAb: Randomized Krylov methods for the approximation of matrix functions (MATLAB)
- FUNM_QUAD: An implementation of a stable quadrature-based restarted Arnoldi method for matrix functions (MATLAB)
Software developed by students:
- VSWorkbench: Extensible VS Code Plugin for incorporating Developer Tools (Bachelor thesis Sufyan Dahalan)
To allow young researchers in numerical linear algebra to also present their work during the Covid-19 pandemic, I organized the online seminar series "Communications in NLA" from September 2020 to May 2021, together with a few colleagues.
All talks have been recorded and can be watched on our Youtube channel.
