I am trying the one in Hapax (e.g., SparseRowMatrix) but it doesn't look so sparse to
me…
Maybe I am doing something wrong.
In any case, at least the data structure for the Yale format shouldn't be too hard to
write.
I'll keep you posted about it.

Thanks. It would be great.
This could also be used for SmallDude.

But I suspect Mondrian to not be efficient on rendering it. I am currently working on a
new rendering engine, and having such large matrixes are one of my primary case studies.

It's a direct port from the one in VW, so I guess there have been some changes due to
different collection classes and implementation details. But I am not knowledgeable enough
in VW and sparse matrix to tell what.
In any case, at least the data structure for the Yale format shouldn't be too hard to
write.
I'll keep you posted about it.
