opf_branch_ang_hess

opf_branch_ang_hess(x, lambda, Aang, lang, uang)

opf_branch_ang_hess() - Evaluates Hessian of branch angle difference constraints.

D2VADIF = OPF_BRANCH_ANG_HESS(X, LAMBDA, AANG, LANG, UANG)

Hessian evaluation function for branch angle difference constraints
for voltages in cartesian coordinates.

Inputs:
  X : optimization vector
  LAMBDA : column vector of Lagrange multipliers on branch angle
        difference constraints, lower, then upper
  AANG : constraint matrix, see MAKEAANG
  LANG : lower bound vector, see MAKEAANG
  UANG : upper bound vector, see MAKEAANG

Outputs:
  D2VADIF : Hessian of branch angle difference constraints.

Example:
    d2VaDif = opf_branch_ang_hess(x, lambda, Aang, lang, uang);
