It looks like Eigen is also developing a multi-array template that they call tensor:

Looks promising…

I almost forgot the main motivation for this replacement, which is that the whole reference-counting mechanism of Blitz++ is mostly an overkill for us, since in our simulations there is always a structure (StateVector or DensityOperator) which is supposed to own the data for the whole lifetime of the program.

What we would need is const and non-const views of this data, the former of which is not very well supported by Blitz++.

A façade to boost::multi_array could be used, along the lines described here:

As underpinning data structure, the blitz::Array could be replaced by boost::multi_array.
This would have the advantage of eliminating dependence on the not too well maintained Blitz++ library.
