I have got a tabulated data-set which contains "@" in its coloum header (e.g name@domain). When loading this table in Matlab (R2017b) this header gets replaced by name_domain.
I need to do some post-processing on the data and the need the correct header back (i.e. with "@") in the final post processed data when saved as ascii file.
How to achive this in Matlab R2017b?

For example,
T = table
name_domain ___________ 1
T.Properties.VariableNames = replace(T.Properties.VariableNames,'_','@')
T = table
name@domain ___________ 1

To be honest, the easiest way would be to upgrade MATLAB releases.
Second easiest way, if you are using MS Windows, would be to generate two seperate files, and then use
system(sprintf('copy "%s"+"%s" "%s"', first_tempfile, second_tempfile, desired_file))
The third easiest way would be to fopen() the file and fprintf() a line at a time, using appropriate formatting.

Thanks for all the answers. Upgrading seems the best way out of this but that is not going to happen any time soon.
