### Vector-valued finite elements

The simplest way to solve vector-valued problems is explained
step-20.
In some situations, in particular if the vector-valued finite
element is composed of scalar elements (for example in linear
elasticity when the displacement in each coordinate direction
is computed, and each vector coordinate is based on a Q(k)
element independent of the other coordinates), then one can do
a few optimizations. However, the situation becomes more
complicated.
step-8
explains the situation in that case.
