I mean something like

DoubleVector x(200), y(200);
double a;

x = a * x + y;

and then, in implementation, use SSE2 or AVX or whatever to speed things up...

At this point, allocation is internal bussines of DoubleVector and alignment does not cause any problems anymore.

Great, that looks cool and makes a lot of sense. I actually use classes like this (no optimzation) just to make some computations code readable. If it would be SSE/AVX optimized, it would definitely give great performance boost to some of my apps.

So I definitelly vote for this option Smile
