It's limited to n*n. Eigen only does square matrices, i.e. width==height.

If you want to know the reason for this design decision, it's that it 
allows to simplify everything a lot and Eigen wants to focus on the 
simple stuff. I should set up an online FAQ, in the meanwhile you can see 
an explanation in this archived mail:
