Hi Luc,
Thanks for the feedback. I did not realize that the check for the

Is performance in LUD normally achieved by fast element access? Or is it
done by using higher order operators on a view of a row (or column)?
I know the the Colt package made the argument that the latter it far

This is often handled by using an offset sparse matrix or vector that is
sparse in that only elements different from the offset are stored. You can
often do this at the algorithmic level by carrying around the requisite
constant matrix in your derivation. Obviously, a normal sparse matrix is a

Hi Ted,
I considered that possibility too, peeked at one of the posts where this
representation was suggested :-).
Pros:
1) the representation is more elegant.
Cons:
1) it would have required me to implement SparseVector, which we should
do anyway, imo. But I wanted to keep the code changes to a
Sujit,
What do you think the trade-offs are between the representation that you
used and another one where you have a Map that contains
rows or columns?

Hello,
I am a new, but fairly happy user of commons-math 1.2 and I have begun
to use it in my code. I needed a sparse matrix implementation for some
data analysis work I was doing, and unfortunately the code with
RealMatrixImpl was coming back with an OOME. So I built a
SparseRealMatrixImpl as a s
