TT-Toolbox 2.1 is released. It contains several bug fixes. My great thanks to Sergey Dolgov for writing many important routines and to Vladimir Kazeev for providing his code for the construction of the QTT-representation of discrete Laplace operator (it can be done for extremely high dimensions in a second!).
TT-Toolbox 2.1 can be downloaded from [drain file 6 url here] or from the page
The [drain file 7 url short introduction] can be also downloaded.
All comments and suggestions are welcome. In the next release we plan to add the conversion procedures from the T. Kolda/B. Bader Tensor Toolbox (conversion from ktensor and sptensor classes), and also to provide more benchmarking examples.
