How do I output the data of each plot in this loop to file? The x variables are the same for all plots while the Y variable changes.

     {
for i=1:2:length(data)
    plot(data{i}.z,data{i}.mass);
hold all
 }

At the end, I would like to have a datafile with several columns like

   {
data{i}.z data{1}.mass data{2}.mass data{3}.mass ...and so on}

Thanks for your help.

Hi!

Look at the commands

fopen
fprintf
fclose

to write to a file. You may use the open/close commands before/after the loop and the fprintf command inside the loop.
