I developed a MATLAB utility function makeBanner.m that renders any string as a comment-block banner in your code, using manually designed ASCII-style characters.
  • Two font modes: 'big' (6 rows, block-style) and 'mini' (3 rows, compact).
  • Supports A–Z, 0–9, and a bunch of symbols (. , : ; ? ! & - _ / \ space).
  • Prints in comment format with borders so you can drop banners directly into code as headings.
  • Perfect for making sections in scripts more readable (and a bit more fun).
Example usage:makeBanner('demo') % mini font (default)
makeBanner('demo','big') % big font
Drop any of these commands in your command window while editing a script and it will print out the banner ready for copying. Hope you people enjoy it as I do =)
