Error in optimization using fmincon

1. Error : Not enough input arguments.

Error in fun (line 4) y = a1*Lh^2*x(1)^2 + b1*Lh*x(1) + a2*Lh^2*x(2)^2 + b2*Lh*x(2) + a3*Lh^2*x(3)^2 + b3*Lh*x(3);

2. Aeq must have one column.

If someone knows please help me out. Thank You.

Please give a full explanation of the problem and copy/pastes of what you are seeing, rather than bullet point.

i tried fixing the problem. This is what i am getting now. --------------------------------------------------

Local minimum found that satisfies the constraints.

Optimization completed because the objective function is non-decreasing in 
feasible directions, to within the default value of the optimality tolerance,
and constraints are satisfied to within the default value of the constraint tolerance.

Looks like you fixed it!
