Refactor `eigsolve` to `fixedpoint` #134

Closed lkdvos closed 5 months ago

lkdvos commented 5 months ago

This replaces eigsolve calls that only ask for the dominant eigenvector with fixedpoint, which just wraps eigsolve and takes the first eigenvalue/vector. The main benefit is that this can now use schursolve instead of eigsolve in the Arnoldi case, and can keep the scalartype real.
