 Workspace provided is     IWORK(      17),  WORK(     192).
 To solve problem we need  IWORK(      17),  WORK(     192).
 
 
 Verification of the constraint gradients.
 -----------------------------------------
 
 The constraint Jacobian seems to be ok.
 
 The largest relative error was    2.29E-07  in constraint    2
 
 
 
 Verification of the objective gradients.
 ----------------------------------------
 
 The objective gradients seem to be ok.
