[Coin-lpsolver] clp duals

Hi,

I am including clp in one of our matlab's project. It's replacing some
lpsolve calls. The problem is that the order of the duals variables we
get from both solvers is not the same ;-)

Here is an example :

CLP		lpsolve

duals =		duals =

   1.0e+04 *	   1.0e+04 *

    0.0001	    1.1281
    1.1281	    0.5339
    0.5339	    0.0001


I'm using the following call from CLP to get the duals (within my mex
file) :

dual = modelPrimalDual->dualRowSolution();

How can I check who is wrong ?

Thanks in advance for any help
