Evaluate the Hessian of the Lagragian.

The Hessian of the Lagragian

The Hessian of the Lagragian is defined as

$H(x, \sigma, \lambda ) = \sigma \nabla^2 f(x) + \sum_{i=0}^{m-1} \lambda_i \nabla^2 g(x)_i$

Parameters:

[in]	n	is the dimension of the argument space for g(x); i.e., must be equal `n_`.
	x	if `values` is not `NULL`, `x` is a vector of size `n` containing the point at which to evaluate the Hessian of the Lagrangian.
[in]	new_x	is false if the previous call to any one of the Evaluation Methods used the same value for `x`.
[in]	obj_factor	the value $\sigma$ multiplying the Hessian of f(x) in the expression for The Hessian of the Lagragian.
[in]	m	is the dimension of the range space for g(x); i.e., must be equal to `m_`.
[in]	lambda	if `values` is not `NULL`, `lambda` is a vector of size `m` specifing the value of $\lambda$ in the expression for The Hessian of the Lagragian.
[in]	new_lambda	is true if the previous call to `eval_h` had the same value for `lambda` and false otherwise. (Not currently used.)
[in]	nele_hess	is the number of possibly non-zero elements in the Hessian of the Lagragian; i.e., must be equal to `nnz_h_lag_`.
	iRow	if `values` is not `NULL`, `iRow` is not defined. if `values` is `NULL`, `iRow` is a vector with size `nele_jac`. The input value of its elements does not matter. On output, For `k = 0 , ... , nele_jac-1, iRow[k]` is the base zero row index for the k-th possibly non-zero entry in the Hessian of the Lagragian.
	jCol	if `values` is not `NULL`, `jCol` is not defined. if `values` is `NULL`, `jCol` is a vector with size `nele_jac`. The input value of its elements does not matter. On output, For `k = 0 , ... , nele_jac-1, jCol[k]` is the base zero column index for the k-th possibly non-zero entry in the Hessian of the Lagragian.
	values	if `values` is not `NULL`, it is a vector with size `nele_jac`. The input value of its elements does not matter. On output, For `k = 0 , ... , nele_jac-1, values[k]` is the value for the k-th possibly non-zero entry in the Hessian of the Lagragian.

Returns:: The return value is always true; see Evaluation Methods.
