TensorNetworkQ
​
TensorNetworkQ
[tn]
yields
True
if
tn
is a valid
TensorNetwork
object, and
False
otherwise.
​
Details and Options
​
Examples  
(11)
Basic Examples  
(1)
Test whether an expression is a valid tensor network:
In[1]:=
TensorNetworkQ[TensorNetwork[{RandomReal[{-1,1},{2,3}],RandomReal[{-1,1},{3,4}]},{{i,j},{j,k}}]]
Out[1]=
True
A network produced by RandomTensorNetwork is valid by construction:
In[2]:=
SeedRandom[42];​​mps=RandomTensorNetwork["MPS"[4,2,2]];​​TensorNetworkQ[mps]
Out[2]=
True
Anything whose head is not TensorNetwork is rejected:
In[3]:=
TensorNetworkQ[{1,2,3}]
Out[3]=
False
