No description provided.

@loiseaujc loiseaujc changed the title arnoldi_preconditioner - A polynomial Arnoldi-based preconditioner for linear systems. This may prove useful later on in neklab when we'll extend it for eigenvalue sensitivity analysis and resolvent analysis where we need to invert $I - \exp(tA)$ repeatedly. arnoldi_preconditioner Feb 2, 2025
