edge case: zero matrix #135

Closed haampie closed 9 months ago

haampie commented 9 months ago

Closes #90

This edge case actually does cover a few things:

  1. Whether ArnoldiMethod recovers in case of getting an invariant subspace
  2. Whether the convergence criterion is correct(<= vs <)
  3. Whether it can deal with backwards substitution of an upper triangular matrix which is singular, when constructing eigenvectors.
