▪
All arguments must represent tensors of the same dimensions.
▪
The sum is exact: cores are combined block-diagonally, so the bond dimensions of the result are the sums of the operands' bond dimensions. Use to reduce the ranks of the result.
▪
Arguments can be tensor trains or raw core lists. Core lists are converted automatically into tensor trains.

Basic Examples
(1)
Sum two tensor trains. Notice their max bond dimensions add up:
In[1]:=
a=TensorTrainDecomposition[RandomReal[1,{1,2,3}]]b=TensorTrainDecomposition[RandomReal[1,{1,2,3}]]TensorTrainPlus[a,b]
