I am trying my hands on examples on genetic algorithms in MATHWORK CENTRAL. I would like someone to explain to me what the empty matix means .I saw it was defined for for equality contraints. But why are there four

function [c, ceq] = simple_constraint(x)
c = [1.5 + x(1)*x(2) + x(1) - x(2);...
-x(1)*x(2) + 10];
ceq = []; by
ObjectiveFunction = @simple_fitness;
nvars = 2; % Number of variables
LB = [0 0]; % Lower bound
UB = [1 13]; % Upper bound
ConstraintFunction = @simple_constraint;
rng(1,'twister') % for reproducibility
[x,fval] = ga(ObjectiveFunction,nvars,...
[],[],[],[],LB,UB,ConstraintFunction)

[x,fval] = ga(ObjectiveFunction,nvars,...
[],[],[],[],LB,UB,ConstraintFunction)
can be rewritten as
A = []; b = [];
Aeq = []; beq = [];
[x,fval] = ga(ObjectiveFunction, nvars, ...
A, b, Aeq, beq, LB, UB, ConstraintFunction)
That is, there are no linear inequality constraints (A and b) and no linear equality constraints (Aeq and beq)
