A few comments :

* prefer operator () to operator[]. operator[] is never needed and is 
less generic
* do you handle multi-dimensional matrix with dim > 2 ?
* separating matrix and vector is a bad idea cause a vector is always a 
matrix. Moreover, you lead the user to wonder about the "orientation" of 
the vector.
* a lot of things need to be doen as policy instead of separate class
* If you want to handle more complex operations, using a NRC allcoation 
schema is better than a sole T* for holding data
* why rewriting expr. tempalte from scratch when proto's around ?
