Matrix / 2D Array Templated Library

So, std::vector is just about the best thing I've come across since sliced bread.

Is there anything along the lines of std:: vector only for 2D arrays / Matrices? I could just go about making a vector of vectors, but I would have thought there is something in the standard template library for this, although from my searching, I haven't come across it.

Do you know of any classes I could use? I'm looking to not reinvent the wheel if it has been done well by someone already.

Thanks for your time and all the help cboard has been already.

just create a structure with every thing you need in the matrix and make a vector of that structure
