Description

Do you have a python version of the function dot with CHUNK_START and CHUNK_END ?

I see the version in python admits only 2 input arguments corresponding to TT1 and TT2 but I need to project as in the matlab version:

% [PR]=DOT(TT1,TT2,CHUNK_START,CHUNK_END[,DO_QR]) If TT2.d>TT1.d, returns a
% tt_tensor obtained from TT2 by projecting its chunk from CHUNK_START to
% CHUNK_END onto TT1. Convenient for extracting slices.

Research direction

Start by locating the Python dot entry point and compare its two-argument interface with the MATLAB DOT signature quoted in the issue. Check how TT1, TT2, CHUNK_START, CHUNK_END, and the optional DO_QR behavior are represented, then verify that the requested chunk projection matches the MATLAB result.
