check_derivatives_for_naninf:

Indicates whether it is desired to check for Nan/Inf in derivative matrices $\;$
Activating this option will cause an error if an invalid number is detected in the constraint Jacobians or the Lagrangian Hessian. If this is not activated, the test is skipped, and the algorithm might proceed with invalid numbers and fail. The default value for this string option is "no".
Possible values:

• no: Don't check (faster).
• yes: Check Jacobians and Hessian for Nan and Inf.
