Once you had created the table described there, you can save() it to a .mat file.
Are you trying to create a text output file or a binary output file?
If you are trying to save to a text file with column headers, then really the best way is to fopen(), fprintf() the headers, fprintf() the data, and then fclose().
If you are trying to save to a text file with column headers, and you really feel a need to use save, then use fopen(), fprintf() the headers, fclose(). Then use
save TheMatFileName -ascii -tabs -append TheVariableName
If you are trying to save in binary form and you need column headers then you need to use a table() object (described in the link above), or you need to use a dataset() object from the Statistics toolbox. Those are the only kinds of rectangular arrays that support column headers.
