How to write linear constraint function in GA ?

Hi

I have an optimization problem written in GA and I want to have the constraints written in the form ax1 + bx2+ cx3 = D, where a, b and c are sources and D is demand and x1...xn are the fractions. So can someone please tell me how to write in matlab? I have written in the form c = ..and ceq =[], but it is showing errors like "too many output arguments"

Take a look at the documentation on linear constraints. For a nonlinear objective with nonlinear equality constraints see this example which uses fmincon as the solver, but the constraint syntax is exactly the same as ga.
