hello

I am going to get exactly the same result for consecutive training of my NN. Every time I train my net the result is different. could you please help me?

[x,t]=bodyfat_dataset;
>> Inputs=cell(1,3);
Targets=cell(1,3);
for i=1:3
Ind=randi(size(x,2),size(x,2),1);
Inputs{i} = x(:, Ind);
Targets{i}=t(Ind); 
end
>> ytotal=0;
>> y=zeros(3,252);
>> net=feedforwardnet;
>> net.divideFcn='';
>> for i=1:3
rng(0);
[net tr y(i,:)]=train(net,Inputs{i},Targets{i});
ytotal=ytotal+y(i,:);
end
..............................
%for the second round of training
ytotal=0;
y=zeros(3,252);
for i=1:3
rng(0);
[net tr y(i,:)]=train(net,Inputs{i},Targets{i});
ytotal=ytotal+y(i,:);
end
% the result is different!!!
