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.

Hi all,
Is there any library for _seriously_ handling/storing sparse matrices in Pharo/Moose?
I was thinking about something like http://en.wikipedia.org/wiki/Sparse_matrix#Yale_format
Thanks.

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.
