% 优化问题：
% min  3x1^2 -1.5x2^2 -5x1 +7x2
% s.t. 3x1 -6x2 <= 35
%      9x1 + 5x2 <= 56
%      x1 >= 2, x2>=0

H = [6 0; 0 -3];
f = [-5; 7];    
A = [3 -6; 9 5;];
b = [35; 56];
lb = [2; 0];
ub = [inf; inf];

[x,fval,exitflag,output,lambda] = quadprog(H,f,A,b,[],[],lb,ub)
% Results: x = [2; 0]；minimum value: 2
