Add a matrix/vector diff testing tool to dune-testtools
I need a testtool that does fuzzy comparison of sparse matrices.
I will implement this, probably along these lines:
- use
MatrixMarket
from dune-istl as output/reference format - provide something equivalent for vectors
- Provide convenience C++ code for the output in dune-testtools
- Do fuzzy comparison in the python wrapper
Any input to this work in progress is welcome in this issue.
