0,‘OK’: Optimization succeeded
1,‘OK/green’: Optimization succeeded, but the sequence of iterates has not yet converged. NPSOL was terminated because no further improvement could be made in the merit function (Mx status GREEN)
2,‘infeasible linear constraint’: The linear constraints and bounds could not be satisfied. The problem has no feasible solution.
3,‘infeasible non-linear constraint’: The nonlinear constraints and bounds could not be satisfied. The problem may have no feasible solution.
4,‘iteration limit’: The major iteration limit was reached (Mx status BLUE).
5,‘not convex’: The Hessian at the solution does not appear to be convex (Mx status RED).
6,‘nonzero gradient’: The model does not satisfy the first-order optimality conditions to the required accuracy, and no improved point for the merit function could be found during the final linesearch (Mx status RED)
7,‘bad deriv’: The function derivates returned by funcon or funobj seem incorrect.
9,‘internal error’: An input parameter was invalid
10,‘infeasible start’: Starting values were infeasible.
