Ok, I'll do that.
Thank you, Jake.

Actually, I built a BlockSparseMatrix some time ago that does this.
It was just like our current row sparse matrix except that it allowed for
blocks instead of rows.
It did assume sparse matrices where the data existed.
Worked a charm on the app in question.
It doesn't appear that I committed
Ted,
Are you going to commit this?

I hadn't planned to since I don't have cycles to properly test it.
Let me see if I can dig it back up to see if anybody else wants to.
SparseMatrix may be good enough for you.

See MAHOUT-1193. Feel free to grab that code, torture it, and tell us if
it is any good.
If it is useful, we can commit it.

Hi,
Using Mahout Matrix interface I want to represent some data where the row
vector is dense iff an instance is associated to this row index, empty
otherwise. The max possible index for rows (a.k.a. rowSize) is defined.
I never query the matrix by column.
I want to be able to add rows if the
SparseRowMatrix?

Robin,
Aren't SparseRowMatrix rows are sparse vectors? In my use case row vectors
don't need to be sparse, they are either full or empty.
