Add option for using LAPACK svd in svd() function

Dear mtfishman, I extended the ITensor in this direction. An svd function takes through the Args system a flag, which selects an svd implementation to use. At the moment, besides...

Add option for using LAPACK svd in svd() function

Hi, I just did the initial commit of ?gesdd. I think there is an opportunity to make ITensor quite flexible and allow implementation of plethora of svd solvers for whomever...

Implementation of LU and Cholesky solvers for linear systems

The use case which led me to include Cholesky & LU comes from the full update algorithm for iPEPS networks. Applying either 2-site gate or 3-site gate leads to a...

Problems running excercise 4

Hi, just add --GLOBALARGS_dtype complex128 In principle this should can be inferred from input file, but right now the dtype has to be explicitly passed in case of computation in...

Two site reduced density matrix for two distant apart sites

Hi, see https://peps-torch.readthedocs.io/en/latest/envs/generic/corrf.html But only correlations along horizontal r=(x,0) or vertical r=(0,y) direction can be computed in this way. Arbitrary coordinates for correlations, i.e. where r=(x,y) cannot computed as easily/efficiently...
