You want to use the fprintf function. See the documentation for it here: https://www.mathworks.com/help/matlab/ref/fprintf.html

The documentation contains information on how to format your output using formatSpec. In your case, you can specify the field width to ensure 'g h i' lines up with 'd e f'. A new line is a special character represented by '\n'. You might also find the example Write Tabular Data to Text File helpful.
