Hi,

I'm working on a project with itensor and needing to solve eigenvalues and vectors of a matrix-like ITensor, e.g., H=ITensor(i,i'), and the bound i.m() <=100 is not large.

Could someone help me out.

Thanks in advance.

Hi, so if you tensor is equivalent to a Hermitian matrix, you can use the diagHermitian function described on this page of the documentation:

http://itensor.org/docs.cgi?page=classes/decomp

Please let me know if that does not give you what you need -

Best regards,

Miles
