Blaze looks nice and easy to use but I will continue to use Eigen since the
data compression aspect is very important to me.
I have read some things about expression templates and would like to apply
this to a pde solver using Eigen as base math library. My problem is how to
vectorize for example:
ddt(T) + div(T) = 0

`What exactly do you want to vectorize here? The calculation of either of
``the addends, or the solution of the resulting system? (I.e. is T a know
``or unknown vector/matrix)
``And actually, expression templates and vectorization are two rather
``different concepts.
`

instead of creating two matrices. But the operations inside the matrix
creation is complex. Depends on numerical method, stencil, etc.
Is anyone working on something similar?

Have you checked OpenFOAM:

(I didn't, I just did some quick googleing)
