Tools for analyzing MFEM Sparse Matricies (among other things)
MFEM does a lot of work with sparse matrixes but does not provide trivial tools to use them. Here I include some basic utilities to analyze these matricies.
Python
There is a python script to preform the actual analysis.
C++
There is a small C++ header only library which provides an interface to write MFEM sparse matrixes out to disk.
The C++ utility writes mfem sparse matricies in a custom format which was written to be simple. The python script only understands this format.
