===============

That doesn't really make sense. Optimal is optimal, and has nothing to do with fmincon. Whatever a piece of code spits out as a solution can be verified as optimal by checking gradients...

1.)
Optimality can be checked, in my case, easily: I minimize kind of a quadratic function. Thus, I can easily check how close to zero my "optimal" value is.

2.)
Unfortunately, I still have no solution to my problem. Any known interference with other packages, parts of matlab, etc.?

Thank you all,
