How to create a multi-line title?

Q: How to create a multi-line title?

Use char function:

 txt=char('First line','Second line','etc');
 title(txt);

The char function is used here to consolidate strings of different length into a single array. You might wish to play around with the alignment:

 h=title(txt);
 set(h,'HorizontalAlignment','Right');
 set(h,'VerticalAlignment','Middle');
