Hadamard product (elementwise multiplication) of two MPSs

[hanfluid]

Hi, could you please recommend an efficient algorithm for performing Hadamard product (elementwise multiplication) of two MPSs based on the TT-toolbox?

Hi, maybe you've already seen this, but this paper presents an algorithm for the Hadamard product of two MPSs. It should be easy to implement in ttpy if you need it. I think this implementation already exists in torchTT.
