% For an active-set solver you probably want to solve
%
% function [x,lambda] = qp(A,b,c,H,x)
%
% Function to solve the problem
%                        minimize     c'x + 0.5 x'H x
%                        subject to   A x >= b

% You may want to have an optional input argument x for the initial
% value of x.

% If you choose to solve by an interior method, you may also want
% to add slack variables s and Lagrange multipliers lambda which gives
%
% function [x,s,lambda] = qp(A,b,c,H,x,s,lambda)
%
% Function to solve the problem
%                        minimize     c'x + 0.5 x'H x
%                        subject to   A x -s = b
%                                     s >= 0
