TT-Toolbox (TT=Tensor Train) Version 2.2.2
TT(Tensor Train) format is an efficient way for low-parametric representation of high-dimensional tensors. The TT-Toolbox is a MATLAB implementation of basic operations with tensors in TT-format. It includes:
tt_tensor
and tt_matrix
classes for storing vectors and operatorsNew in Version 2.2.2
subsref
and subsassgn
now possible for tt_matrix
:
current_value=ttm(123,4567)
and ttm(123,4567)=new_value
ttm2=ttm([1 2 7],[1 2 1;1 1 2])
For additional help see code of @tt_matrix/subsref.m
and core/tt_submatrix.m
New in Version 2.2.1
ttM=tt_blockwise({ttA ttB ttC;ttD ttE ttF})
ttv2=ttv(1,2,:,2,2,:,:,:,1)
or ttv2=ttv({1,2,':',2,2,':',':',':',1})
