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.

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.

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

SparseMatrix is implemented as a Map, you could modify
that class to allow you to chose between dense or sparse rows at
construction time.

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.

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 row
12 matches
