[Coin-discuss] Handles to different OSL storage modes

[Laszlo Ladanyi]

It's already there :-). Well, sort of...

OSL itself will use a column major ordered representation, since that's how it
was written. However, it is possible to talk to OsiOsl in row major ordered
format. Extracting the matrix is simple: getMatrixByRow(). Feeding the matrix
in as almost as simple: just load the problem matrix into a CoinPackedMatrix
first (which can be row or column major ordered) than call that version of
loadProblem() that takes a CoinPackedMatrix as argument.

I hope this helps,
