Subject: Re: [ublas] [GSoC 2019] Possible Mentorship for a project on implementing uBLAS tensor product and decomposition algorithms

Hello Thomas,

thanks for considering Boost/uBLAS.

The current tensor implementation does not provide any alternative tensor
representation such as the tucker, cp or the tensor-train format. We want
to definitely support such representations and according operations.
However, this year the focus is more on the dense structures. On the long
run it would be good for Boost/uBlas to support the above mentioned types
and operations.

Your matrix expressions do not include expression templates. Are you going
to add this feature?
If you have resources and time left, please write your proposal (google
documents) and share the link of your proposal directly with me.
