Fprintf question and application.

fprintf( '%7sVIII\n', 'Henry' )
fprintf( '%1sVIII\n', 'Henry' )

I can't understand the difference between the two. They have the same output. How does the field size value effect the fprintf?

Write this, you will understand

fprintf( '%50sVIII\n', 'Henry' )

So does this sort of create an empty string before Henry. Why does it add VIII later then?

[Azzi Abdelmalek]

%50s, will be replaced by a string 'henry' with length equal to 50 characters, that's why you 45 blanks and the five character of 'Henry'.

VIII? because you add it!

I cant figure out how this function works completely, I did check MATLAB help, hoping that this example can help clear it up.
