[Coin-lpsolver] Using ClpCholesky??? classes for computing projections

[John J Forrest]

Mikhail,

What you probably want is some simplification of findDirectionVector in 
ClpPredictorCorrector class.  See if you can figure out what you would 
need.

[Coin-lpsolver] Using ClpCholesky??? classes for computing projections






Dear COIN Community,

I am implementing a numerical procedure which already uses ClpInterior
to solve LPs. In this procedure, I also need to frequently compute
projections on the subspace of LP's equality constraints. While I can
certainly use some other linear algebra packages to do that, I was
wondering if such functionality is already provided in some convenient
way by ClpCholesky??? classes. Unfortunately, I was not able to
immediately figure that out by looking at the source.

Thanks for any advice.

Best,
Mikhail Nediak
