The following files accompany the paper https://arxiv.org/abs/1908.11413
The examples use the following datafiles which must be downloaded and placed into the folder indicated in the code. Moreover, the TT-toolbox (https://github.com/oseledets/TT-Toolbox) and tensor toolbox (http://www.tensortoolbox.org/) need to be installed to run the examples using the tensor-train or the canonical decomposition, respectively.

each of these run a different example
ex_2d.m
ex_aviris.m
ex_bootstrap.m
ex_mall.m
ex_samson.m
ex_urban.m
ex_watersurface.m
check_recovery.m - confirms local convergence guarantees
iterate_multiscale_TT.m/iterate_multiscale_candecomp_f.m - runs the alternating decomposition algorithm into
the multiresolution TT-format/canonical format
one_iteration_TT.m/one_iteration_candecomp_f.m - finds the optimum scale tensor at a given scale.
