I have a constrained minimization problem with objective function (in simplified form)
z=b1+p1*log(p1/(p1+p2+p3))+b2+p2*log(p2/(p1+p2+p3))+b3+p3*log(p3/(p1+p2+p3))where b1=a1*2,%(a1 is a constant input)
b2=a2*3,%(a2 is a constant input)
b3=a3*4,%(a3 is a constant input)
and constraints2*p1+3*p2=A1,%(A1 is a constant input)
3*p2+5*p3=A2,%(A2 is a constant input)
p1>=0,p2>=0,p3>=0,so, I wrote on my script a1=input('a1=');a2=input('a2=');a3=input('a3=');A1=input('A1=');A2=input('A2=');A=[-1,0,0;0,-1,0,0;0,0,-1];B=[0;0;0];Aeq=[2,3,0;0,3,5];Beq=[A1;A2];optimal_p1p2p3=fmincon(@fozw,[0.1;0.1;0.1],A,B,Aeq,Beq);function z=fozw(w);p1=w(1);p2=w(2);p3=w(3);z=b1+p1*log(p1/(p1+p2+p3))+b2+p2*log(p2/(p1+p2+p3))+b3+p3*log(p3/(p1+p2+p3));endendThen, when I run the script. It appeared on command window solver has stop prematurelyfmincon stop because it exceeded function evaluation limitoptimal_p1p2p3=NaNNaNNaN
What is the possible error?.
