error in fmincon code
显示 更早的评论
Hi community,
I am busy optimizing a function in fmincon, I think I have all parameters set up correctly. However I get an error when I am running the code. I think the problem lies in my objective function.
%V=[V(1) V(2) V(3)]=[Y(1) Y(2) Z(1)]
l = 0.4;
q = 6;
s = [2;2.2];
A1 = [1,1];
x = [20; 25];
d = 80;
V0=[1,2,4];
objective = [-s.',(l-q).']; %(l-q).'*y-s.'*z; %[ Y, Z] tried both of these
% X(1)=V(1)+A1(1)*V(3) X(2)=V(2)+A11(2)*V(3)
Aeq = [eye(2), A1.']; %=[1 0 A1(1);0 1 A1(2)]
beq = x;
lb = [0, 0, 0]; %requires 3 bounds as there are 3 variables
ub = [Inf, Inf, d];
sol = fmincon(objective,V0,[],[],Aeq,beq,lb,ub);
y = [sol(1);sol(2)]
z = sol(3)
error that pops up is
Error in probeerfmin (line 14)
sol = fmincon(objective,V0,[],[],Aeq,beq,lb,ub);
Thankyou!

V0 = [1;2;4];
objective = @(V)[-s.',(l-q).']*V;
But why do you shoot with canons on sparrows (means: why do you use a nonlinear optimizer for a linear problem) ?
