Verification of the objective gradients.
----------------------------------------

All objective gradient elements have been set.

Simple Check:

The Jacobian seems to be ok.

The largest relative error was 1.04e-08 in subfunction 3  


Verification of the constraint gradients.
-----------------------------------------

All constraint gradient elements have been set.

Simple Check:

The Jacobian seems to be ok.

The largest relative error was 1.91e-08 in constraint 1
