[Coin-discuss] CoinBuild / CoinPackedMatrix

[John J Forrest]

Matt,

CoinModel is definitely what you want.  You could just use some dummy stuff
for bounds etc and then use the standard Osi or Clp CoinModel calls.

CoinModel can have names  as elements e.g. 2.1*C00001.  If it has then
C00001 would have been associated with a value and that is the array you
would pass - modelObject.associatedArray() see.line 654 in
OsiSolverInterface.cpp.

Sorry I can't help more - but I think I am going to be mostly off-line for
a few weeks.

John

No info in comments, and createPackedMatrix is not in unitTest. There is
an "associatedArray( )" access method, but if that was correct,
createdPackedMatrix could just access it directly from within the object
- so I am not sure what the argument is for.
