作业帮怎么用matlab求一个三元二次函数的最小值?函数是Y= -22.92X1+52.32X2+10.90X3+2.62X1X2-11.41X1X3+17.93X2X3+1.58X1^2-28.57X2^2+18.11X3^2+220.65,X1,X2,X3的取值范围都是[-1.682,1.682],希望能给我写一下具体的编程,还有X0

Y=@(X) -22.92*X(1)+52.32*X(2)+10.90*X(3)+2.62*X(1)*X(2)-11.41*X(1)*X(3)+17.93*X(2)*X(3)+1.58*X(1)^2-28.57*X(2)^2+18.11*X(3)^2+220.65;
x0=[1 1 1];lb=-1.682*[1 1 1];vb=1.682*[1 1 1];options = optimset('algorithm','active-set');
[X Y]=fmincon(Y,x0,[],[],[],[],lb,vb)
按上面语句试试
