-> SparseNonlinearProgramDerivatives

Parameters

jacobianPattern Action<Action<Int32, Int32>>: Emits zero-based constraint-row and variable-column indexes.
jacobian Action<Vector<Double>, Action<Int32, Int32, Double>>: Emits Jacobian entries at the supplied point.
lagrangianHessianPattern Action<Action<Int32, Int32>> (Optional): Emits lower-triangular Hessian indexes, or is null for limited-memory curvature.
lagrangianHessian Action<Vector<Double>, Double, Vector<Double>, Action<Int32, Int32, Double>> (Optional): Emits Lagrangian Hessian entries, or is null to approximate curvature.

Exceptions

ArgumentNullException	A Jacobian callback is null.
ArgumentException	Hessian values are supplied without a Hessian pattern.
