Matrix classes in C ++

Question

I am doing math with linear algebra and was looking for some really easy and easy to use matrix class that could handle different sizes: basically 2x2, 2x1, 3x1 and 1x2. I suggest that such a class can be implemented using templates and in some cases use some specialization for performance. Does anyone know of any simple implementation available for use? I don’t want “bloated” implementations, as I will run this in an embedded environment where memory is limited.

thanks

How easy is it to store a matrix in an array, for example

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

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