Sure! Cool! I mean, for the moment being, that seems
nice. Could you please bother doing that ASAP?

And one remained point: Does that take after Boost,
and, more specifically, uBLAS? (Although I'd
understand that as soon as I see the code.)

Hmmm... This time, it was the vague of a general
system of n equations to be solved for n variables.
But that just made me curious to find it in the Boost.
And that's not why I'm likely to need it in the
future. That is, if you want to know the reason, you
should wait until I use them in a more real problem. 

However, as I told previously, I find lack of it a big
shame for a high-brough developped library such as
Boost. Consider further the lack of determinat, etc.

All of the Best,
