This is an optimization (elimination of temporaries, lazy evaluation), but more importantly this allows for a much nicer API, especially as Eigen supports lvalue expressions. For example, the following is valid with Eigen and compiles to optimized code:
\code matrix.row(i) += factor * matrix.row(j); \endcode</li>

all usual optimizations in the case of fixed size, such as loop unrolling.</li>
<li>Both column-vectors and row-vectors are supported, as special cases of matrices.</li>

<h2>Compiler Support</h2>
Eigen is standard C++98 and so should theoretically be compatible with any compliant compiler. Of course, in practice, things are slightly different.
Eigen is well tested with recent versions of GCC and gives very good performance with GCC 4.2. For some reason the performance is not so great with GCC 4.1.
Eigen is also well tested on ICC, and gives even better performance with it than with GCC 4.2.
