Hi,

I was wondering if there's a code that supports Eigen for tensor product. More specifically I need three functions:

ttv - tensor times vector
ttm - tensor times matrix
ttt - tensor times tensor

For example, In matlab I use the tensor toolbox:

http://www.sandia.gov/~tgkolda/TensorTo ... x-2.5.html

which supports these functions for dense and sparse tensors.

Thanks

search for tensor in this forum, I remember there have been some related discussion. I also found this: http://code.google.com/p/ndarray/, though it seems a bit outdated.

I found:

viewtopic.php?f=74&t=86947&p=153378&hilit=tensor#p153378

and I understand that Eigen supports only 1D and 2D arrays. N-array isn't the whole story, more importantly I need n-mode multiplication as I noted above.

Thanks, I'll keep looking.
