# DS_STATE_INTERMEDIATE

The `DS` object is a intermediate state, where the matrices have been reduced to an intermediate form, but the solve is not finished completely.

## Note

In some cases the solve starts at the intermediate stage, e.g., in Lanczos methods the projected matrix is already in tridiagonal form.
