Implement krylov space analysis in tensorflow #3

Closed maniospas closed 2 years ago

Implement krylov space analysis for the tensorflow backend. This could require defining additional backend operations.

Implemented krylov space operations for all backends and switched internal representations to be of one-dimensional tensors. Results are working correctly even in highly-complex settings. Related tests pass under all backends.
