Matrix classes in c++

Question

I'm doing some linear algebra math, and was looking for some really lightweight and simple to use matrix class that could handle different dimensions: 2x2, 2x1, 3x1 and 1x2 basically. I presume such class could be implemented with templates and using some specialization in some cases, for performance. Anybody know of any simple implementation available for use? I don't want "bloated" implementations, as I'll running this in an embedded environment where memory is constrained.

Thanks

Answer 1

How about just store the matrix in an array, like

2x3 matrix = {2,3,val1,val2,...,val6}

This is really simple, and addition operations are trivial. However, you need to write your own multiplication function.

Another option, altough may be too late is:
