Hi,

would it be possible to add constexpr support for the fixed size matrices
in Eigen?

Best regards,

Hi!

Have a look at this discussion/feature request:
http://eigen.tuxfamily.org/bz/show_bug.cgi?id=820

Short summary: Theoretically, it could be possible.
Biggest issues are that data members must be initialized by
mem-initializer (they can be overwritten afterwards, though), and more
important that SIMD-intrinsics don't work at the moment (afaik).

I don't know of any active development in that area, but feel free to
experiment in that direction.

Cheers,
Christoph
