Hello everyone,

I am trying to do an maximiztion with optimization toolbox using genetic algorithm solver. What i am trying to do is i have a function with 2 parameters and 1 variable. I have a for loop and in the loop i wanna do this.

for i = 1:1

for j = 1:1296

z = z + (-1)*(xij(36*i+j-36)*aii(i,j)*r(i,j));

end

I wanna multpily the x,r, and a for each iteration and sum every iteration.

like this;

for (1,1)

x(1,1)*r(1,1)*a(1,1) = 188

for (1,2)

x(1,2)*r(1,2)*a(1,2)=74 +188= 262 (you get the idea)

Any suggestions on how to do this?

Because when i write it this was i get an error.

z = z + (-1)*(xij(36*i+j-36)*aii(i,j)*r(i,j));

Thank you in advance,

Beyza.
