Have you looked at eigen?

The quality of the lib is certainly high enough to be in boost IMO, but I'm sure there's some reason why it isn't.
That said AFAIK the full tensor support (i.e. beyond 2 dimensions) is currently experimental.

Subject: [boost] tensor library
Hello everyone,
I am new in the community. I would like to ask, how interesting would be to
have in boost a new container with multiple indices (tensor) using variadic
templates. I know that Boost.MultiArray library already exists in boost.
However I think it does not fulfill the readability and
friendliness of something like:
newlib::tensor<3,double> t(2,2,3);
t(0,0,0)=1;
also with extra possibilities similar to Matlab/Octave
t(newlib::all,1)=0;
I would also like to add mathematical operations
t1=t2+t3;
using lazy evaluation like in armadillo package or in the David Abrahams
and Aleksey Gurtovoy book (C++ Template Metaprogramming: Concepts, Tools,
and Techniques from Boost and Beyond). I fell that something similar
to this is very important for numerical calculations and somehow it is
not a standard in C++ (maybe I am missing something).
Best regards, Paulo
