Matrix Product Toolkit | Itools / Mp-iinfo

mp-iinfo is the iMPS counterpart of the mp-info command. It displays various bits of information about an iMPS, including the size of the unit cell, the number of states kept at the unit cell boundary, the von Neumann entropy at the unit cell boundary, and the orthogonality fidelity. (The orthogonality fidelity is not so relevant; for an orthogonal state this is numerically zero.)

It can also display some information for each partition of the unit cell, such as the density operator, number of states, and entropy. As of 18-11-2009, not all options work correctly.
