Description
            This is the interface between Scilab and IPOpt, the solver for non linear
constrained optimization problems. IPOpt is available at https://github.com/coin-or/Ipopt.

Features
--------

The current module provides the following functions :

 * ipopt : Scilab interface to the IPOpt optimizer

The module has the following features :

  * Manages nonlinearily constrained optimization problems.
  * Manages the sparsity pattern of the gradient of the constraints.
  * Manages the sparsity pattern of the Hessian of the Lagrangian.
  * Allows to use Scilab sparse matrices instead of triplets (new 1.1 feature) 
  * Manages the linearity of the variables, of the constraints.
  * Uses Mumps as the sparse solver (Paradiso for the windows version).
  * Manages functions provided as macros, or as compiled externals (Fortran or
C).

Troubleshooting (Windows only)
------------------------------

With the actual version of Scilab (6.1) there is a mismatch between the version
of Intel Fortran runtime used by Scilab and Ipopt library. The first time you
load the toolbox, you will see the following error:

atomsLoad: An error occurred while loading 'sci_ipopt-1.1':
exec: error on line #33: "link: The shared archive was not loaded: Unknown
Error"

To fix this, just type the following and restart Scilab:

exec(atomsGetInstalledPath("sci_ipopt")+"\windows_ifort_fix.sce")

If you get an error you may have to gain administrator rights before launching
Scilab.
