This is an implementation Stroustrup provides as a pedagogical example:

http://www.research.att.com/~bs/matrix.c

It depends a whole lot on what you want to do. There are lots of math
related classes in products such as Coin3d.
http://www.coin3d.org/

Boost has some Math related stuff:
http://boost.org/libs/libraries.htm#Math

This is linked from Stroustrup's homepage:
http://www.osl.iu.edu/research/mtl/

There's some stuff here that might be in the neighborhood of what you want:

poke around here as well:

the time has come to be serious about macro-free C++ programming." - B. S.

If performance is an issue try LAPACK/BLAS. Its native language
is Fortran, but it interfaces well with C++.
