Let say i have this simple loop,,
for i=1:3
A=x((i-1)*3+1);
B=x((i-1)*3+2);
C=x((i-1)*3+3);
Z=A*B+C*A;
end
i want the value of C in each loop to be sum and then using it in this eq let say,
W=E-C
because the value of C are different in each loop.
Thanks ^_^.

Say E=3;
for i=1:3
A(i)=x((i-1)*3+1);
B(i)=x((i-1)*3+2);
C(i)=x((i-1)*3+3);
Z(i)=A*B+C*A;
W=E-sum(C);
end

What do you mean you want the Z as constraint? Can you explain what you want output to be in more detail please? Or give an example with numbers?
