function c= opt(x)
%x=[20,40,60,80,100,120,140,160];
x=20:20:160
p1 = -0.0001759;
p2 = 0.03395 ;
p3 = 5.987 ;
c = p1.*x.^2 + p2.*x + p3;
disp(c);
plot(x,c);
end
Can anybody help to resolve the error

@esiotlab GEC - it looks like your fitness function is returning an array. You must change your code so that a scalar is returned.
It also looks like you are overwriting the input variable x with an array of values. Why? This defeats the purpose of using the algorithm since all results returned by your fitness function will be the same.

@esiotlab GEC - if you wish to discuss the problem here in the forum, then please do so.

I can't decipher from function "opt" what you are trying to minimize.
But anyhow: your c has dimension 1x8, but it has to be 1x1.
