		double *	cubptr
	)			`[virtual]`

overload this method to return the information about the bound on the variables and constraints.

The value that indicates that a bound does not exist is specified in the parameters nlp_lower_bound_inf and nlp_upper_bound_inf. By default, nlp_lower_bound_inf is -1e19 and nlp_upper_bound_inf is 1e19. (see TNLPAdapter)

Implements Ipopt::TNLP.

		double *	variables,
		bool	initializez,
		double *	zl,
		double *	zu,
		int	numConstraints,
		bool	initializeLambda,
		double *	lambda
	)			`[virtual]`

overload this method to return the starting point.

The bools init_x and init_lambda are both inputs and outputs. As inputs, they indicate whether or not the algorithm wants you to initialize x and lambda respectively. If, for some reason, the algorithm wants you to initialize these and you cannot, set the respective bool to false.

Implements Ipopt::TNLP.

virtual bool MatlabProgram::eval_f	(	int	numVariables,
		const double *	variables,
		bool	ignoreThis,
		double &	objective
	)			`[virtual]`

overload this method to return the value of the objective function

Implements Ipopt::TNLP.

virtual bool MatlabProgram::eval_grad_f	(	int	numVariables,
		const double *	variables,
		bool	ignoreThis,
		double *	gradient
	)			`[virtual]`

overload this method to return the vector of the gradient of the objective w.r.t.

Implements Ipopt::TNLP.

virtual bool MatlabProgram::eval_g	(	int	numVariables,
		const double *	variables,
		bool	ignoreThis,
		int	numConstraints,
		double *	constraints
	)			`[virtual]`

overload this method to return the vector of constraint values

Implements Ipopt::TNLP.

virtual bool MatlabProgram::eval_jac_g	(	int	numVariables,
		const double *	variables,
		bool	ignoreThis,
		int	numConstraints,
		int	sizeOfJ,
		int *	rows,
		int *	cols,
		double *	Jacobian
	)			`[virtual]`

overload this method to return the jacobian of the constraints.

The vectors iRow and jCol only need to be set once. The first call is used to set the structure only (iRow and jCol will be non-NULL, and values will be NULL) For subsequent calls, iRow and jCol will be NULL.

Implements Ipopt::TNLP.

virtual bool MatlabProgram::eval_h	(	int	numVariables,
		const double *	variables,
		bool	ignoreThis,
		double	sigma,
		int	numConstraints,
		const double *	multipliers,
		bool	ignoreThisToo,
		int	sizeOfH,
		int *	rows,
		int *	cols,
		double *	Hessian
	)			`[virtual]`

overload this method to return the hessian of the lagrangian.

The vectors iRow and jCol only need to be set once (during the first call). The first call is used to set the structure only (iRow and jCol will be non-NULL, and values will be NULL) For subsequent calls, iRow and jCol will be NULL. This matrix is symmetric - specify the lower diagonal only. A default implementation is provided, in case the user wants to se quasi-Newton approximations to estimate the second derivatives and doesn't not neet to implement this method.
