QTT_FFT

Open distone opened this issue 6 years ago • 4 comments

This toolbox's Matlab version includes a nice and powerful QTT_FFT function which does FFT on tensors in QTT format, but I didn't find it in this python implementation.

It would be very much helpful if this feature was added to the project.

Ok, I would do it. Would try to add the QTT_FFT functions to the project, just translate from the Matlab counterparts of Oseledets' TT-Toolbox project.

Feel free to pull request into the develop branch

seems the "tt_qr" and "chunk" function are also not yet available in python, they are needed by the n-D QTT_FFT. or, are they already there and I failed to found?

The "rounding" function is already there, so seems some Fortran code for "tt_qr" should be available there. Do anyone knows how to call the Fortran tt_qr in python?
