Bug posted by @egboman . Original text:
I need to read MatrixMarket files with no values (pattern only) into Tpetra for Zoltan2 testing. Ideally, I would like to get a CrsGraph returned from the Tpetra::MatrixMarket::Reader. I don't see how to do this?
A work-around would be for Tpetra::MatrixMarket::Reader to create a CrsMatrix with explicit zeros. Then I could extract the graph from the matrix.
