Genetic Algorithm Fails at galincon Line 99

I have built a genetic algorithm that is basically defined as following:

y=ga(@fitnessFunction,Vars,[],[],[],[],lb,ub,[],options);

The function was working fine as I was not using any linear and non-linear constrains, thus A,b,Aeq,beq are empty arrays. Today I got a matrix multiplication error, and the code was crashing on line 99 in galincon, on the following code.

output.maxconstraint = norm([Aeq*x'-beq; max([Aineq*x' - bineq;x' - ub(:);lb(:) - x'],0)],Inf);

Where Aeq, bineq are 0x10 matrices, thus Matlab does not regard them as empty. I have just commented the line out for now as it is not needed in my code. Let me know if you have any answers, please.
