all usual optimizations in the case of fixed size, such as loop unrolling. Moreover
special care is used to ensure that the fixed-size types never cause dynamic memory
allocations. Even when the dimensions of an expression at not known at compile-time,
if a fixed bound is known (e.g. when taking a block in a fixed-size matrix) then
Eigen uses it to allocate a static array instead of a dynamic one.</li>
<li>Both column-vectors and row-vectors are supported, as special cases of matrices.</li>
<li>The following scalar types are supported and well tested: \c int, \c float, \c double,
