Hi All, I am making several plots on each other using the command:

 {
figure(1); clf
for i=1:2:length(data)
    plot(data{i}.number,data{i}.amount);
    hold all
end
 }
where data{i}.number should be identical for all data{i}.amount.

Now I am interested in writing the values of each plot into a .txt file so I can process it elsewhere. I have tried:

{
for i=2:2:length(data)
  dlmwrite('amount.txt', [data{i}.number, data{i}.amount],'delimiter','\t');
end
hold all
}
but it only writes one dataset. What I want is an 'amount.txt' file with the following column format:
{
  data{i}.number data{1}.amount data{2}.amount data{3}.amount ...
}
