% Update the position and velocity of each particle (except the elites)
max_iter=300;
b=0.6;
mu=2.34;
x(1)=0.6;
for k=1:max_iter
if x(k)<0.7
x(k+1)=b*mu*x(k)+x(k)*(1-b);
end
if x(k)>=0.7
x(k+1)=b*mu*(1-x(k))+x(k)*(1-b);
end
rvalue=(x(k+1));
end
for i = OPTIONS.Keep+1 : OPTIONS.popsize
r = rvalue(3,OPTIONS.numVar); %Error of matrix exceeds dimensions
x = Population(i).chrom;
deltaVpersonal = OPTIONS.c1 * r (1,:).* (pbest(i).chrom - x);
deltaVswarm = OPTIONS.c2 * r(2,:) .* (gbest.chrom - x);
deltaVneighborhood = OPTIONS.c3 * r(3,:) .* (nbest(i).chrom - x);
vel(i,:) = OPTIONS.w * vel(i,:) + deltaVpersonal + deltaVswarm + deltaVneighborhood;
Population(i).chrom = x + vel(i,:);
end

Either rvalue does not have 3 or more rows, or rvalue does not have OPTIONS.numVar columns. What does this show in the command window if you put it before that line?
size(rvalue)
OPTIONS.numVar
