I'm running this code on matlab but in the last loop matlab is just displaying answers of last column and not all loop values.
demand=[25,25,10];
cost_per_unit_energy=[0.01;0.02];
RM1=[1 0];
RM2=[0 1;1 0];
RM3=[1 0];
RM4=[1 0;0 1];
Make_topart_power=[12 10;8 9;10 10;9 7];
S1=[2 3 0 0;2 0 2 3];
S2=[4 0 0 1;0 2 3 0];
S3=[2 0 2 0;3 2 0 0];
E= [S1;S2;S3];
Ez = [size(S1,1) size(S2,1) size(S3,1)];
Ec = [0 cumsum(Ez(1:end-1))];
Ea = allcomb(1:Ez(1),1:Ez(2),1:Ez(3));
En = size(Ea,1);
R = cell(1,En);
for r=1:En
R{r} =E(Ec+Ea(r,:),:);
end
RM= [RM1;RM2;RM3;RM4];
RMz = [size(RM1,1) size(RM2,1) size(RM3,1) size(RM4,1)];
RMc = [0 cumsum(RMz(1:end-1))];
RMa = allcomb(1:RMz(1),1:RMz(2),1:RMz(3),1:RMz(4));
RMn = size(RMa,1);
S = cell(1,RMn);
for s=1:RMn
S{s} =RM(RMc+RMa(s,:),:);
end
for s=1:numel(S)
power_consumption{s}=bsxfun(@times,S{s},Make_topart_power);
end
for r=1:numel(R)
for s=numel(power_consumption)
Energy_consumed=bsxfun(@times,(R{r}*power_consumption{s}),demand');
cost=bsxfun(@times,Energy_consumed',cost_per_unit_energy);
energy_cost(r,s)=sum(sum(cost));
end
end
Output=
energy_cost(r,s)=
[0 0 0 31.9000000000000
0 0 0 32.7000000000000
0 0 0 27.9000000000000
0 0 0 28.7000000000000
0 0 0 41.4000000000000
0 0 0 42.2000000000000
0 0 0 37.4000000000000
0 0 0 38.2000000000000]
somebody please help me I've tried one by one value checking using debug but it changes value for zero elements sometimes. what should I do?

In the line “for s=numel(power_consumption)” you should have written:
for s=1:numel(power_consumption)
