SpectraSymGEigsShiftSolveris an iterative meta solver that finds eigenvalues of a system by solving a sequence of linear systems. Until now, the solver used for these subproblems was hard-coded toEigenSparseLUSolver. This PR adds support for any registeredLinearSolverto be used to solve the subproblems.Related issues and PRs:
FYI @takeshimg92 @philbucher @aronnoordam
This PR requires some sparse matrix utilities from #13645.
