[scilab-Users] Integration between LPSolve and Scilab

Hi,
As far as I know, the lpsolve interface is not available for Scilab 5.3.
It is not available in ATOMS. A linear solver which is available in
Scilab 5.3 is linpro, from the quapro module :
http://atoms.scilab.org/toolboxes/quapro
Is there a reason why you specifically need the lpsolve module ?
Best regards,
Michaël Baudin
