<br>
it is true, I couldn't produce any meaningful results using <i>fmincon</i>
in Scilab 5.4.1, while the module worked perfectly in the previous
version (Scilab 5-3.3).<br>
However, running the nonlinear constrained optimization problem in
Scilab proved rather slow.<br>
Scilab required the triple time for the solution of the program
with respect to Matlab.<br>
At this point I should add that I was very careful to use the same
optimset in both Scilab and Matlab runs.<br>
<br>
Does anyone have any experience in <i>fmincon</i> time
performance in Scilab?<br>
<br>
PS. Stéphane, is the fsqp toolbox accessible to all Scilab users?<br>
<br>
Thank you for your attention, Natasha<br>

Currently, sci_ipopt seems to be broken on Linux and MacOSX when
using the atoms package for Scilab 5.4.1. Since fmincon relies
on sci_ipot, fmicon is equally broken... BTW, users needing an
optimization toolbox with general non-linear constraints are not
lucky with Scilab. As far as I am concerned, I still use fsqp,
which cannot be easily released as an Atoms module because of
proprietary code. But Ipopt is said to really outperform fsqp,
so I am rather impatient to see it coming. <br>
<br>
As it is the only module of this class/kind (optimization +
complementary module), the Scilab team should take care of the
functionnality of it when new versions of Scilab are released.<br>

<pre>Hello everyone! I am a new Scilab 5.4.1 user (in Ubuntu 12.04.4).
I installed fmincon 0.3.1-1 using atoms, but when I tried it on the first
help example I obtained a rather weird output:
fval = 0.
x = 10^(-318) * Inf Inf
Could anyone help me please?
Thank you in advance, Natasha
