[Coin-lpsolver] clp duals

[John J Forrest]

Didrik,

Without the matrix it is impossible to make any comments.

If you wish, you may send me a matrix where this occurs with the two 
outputs.

[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
