How do I use this algorithm? What does that parameter do?

### How to convert iMPS to finite MPS?

I have an iMPS as the result of an iDMRG run. By calling

Code: Select all

psi.enlarge_mps_unit_cell(m)
I can easily increase the number of sites in the unit cell, however it is still in iMPS form.
Would it work if one calculates the canonical_form with setting the bond dimension to chi = 1 at the boundary?
