WebThe key is to use the ITensor::visit (or IQTensor::visit) method. You pass this method any function which takes either a Real or Cplx argument (or both) and it plugs each element … WebITensor is a system for programming tensor network calculations with an inter-face modeled on tensor diagrams, allowing users to focus on the connectivity of a tensor network without manually bookkeeping tensor indices. The ITensor in-terface rules out common programming errors and enables rapid prototyping of
