I have a list, call it mylist, made of many sublists that are just points from a plot and I would like to export that to a single file. Let's say I have, for example, something like this
mylist1={{1,2},{3,4}};
mylist2={{5,6},{7,8}};
mylist={mylist1,mylist2};
I need an output file like
1 2
3 4
5 6
7 8
(notice the empty line between the two sublists). If I do
Export["myfile.txt", mylist1, "Table"]
I obtain a file with
1 2
3 4
which is ok for a single sublist, but I don't know what to do in order to export all the sublists to the same file separated by an empty line.
