a thought about operations tweaks
one may want to tile and/or partially unroll operation loops but since such thing characterize operations rather than objects themselves it is wrong to tag the objects with such info consider
matrix<double, tile<3, 3> > tiled1; //the first one //... matrix<double, tile<3, 1> > tiled2; //far from the first one //... matrix<double> result = tiled1*tiled2; //what tiling would occure In those cases, we compute the smallest common multiple of tiling shape as stated in all loop optimization techniques paper.
