VERSION: Tensor 3.5.8 Symmetry 4.5.0 eigvalue 4.0 optimization 1.0.0

Tensor Network State Package(libTNSP) is a library of Fortran 90 with subroutines or function for Tensor Network states(TNS). It is freely-available software, and is copyrighted. If you have any question, send email to Shaojun Dong via

The distribution tar file contains the Fortran source for libTNSP and the testing programs, which is a PEPS with simple update method. To compile the libTNSP, one should link the package to the lapack and blas.

• libTNSP can be installed with make. Configuration have to be set in the make.inc file. A make.inc for a Linux machine(ubuntu16.04) running GNU compilers is given in the main directory.

• Do "make" in the current directory to build the standard library "libTensor-3.1”. And other codes for makefile are:

            make : installed the package with the configuration
                   in the file make.inc
  
  
      make clean : clean the files of *.o and *.mod according 
                   to the file make.inc
  
   make cleanAll : clean all the files of *.o, *.mod and the package
  
   make cleanlib : clean the package according to the file make.inc
   
  make cleanAlllib : clean All the packages
  
  make cleanAllMod : clean All the file of *.mod *.o
  

• Use the code

  "-I$(libTNSP)/libTensor-$(version) -L$(libTNSP)/libTensor-$(version) -llibTensor-$(version)"

to link your code with the libTNSP, where $(libTNSP) is the libTNSP directory. And make sure you have linked the libTNSP with the blas and lapack. If you use the package of eigvalue-4.5.0, the arpack is needed.

• you can look for PEPS/makefile to see how to compile and link libTNSP

• The libTNSP can not run under Windows yet. It test OK in linux and Mac.
