farg: a pedestrian M-file parser showing all used functions' syntax

parses an M-file searching for functions and prints their exact, literal syntax

FARG parses an M-file (function or script) searching for function tags and lists their exact, literal syntax.

in addition, FARG displays a wide variety of file statistics.

currently, these functions are detected and listed
- main function
- subfunctions
- nested functions
- anonymous functions
- eval class calls
- unresolved calls

whitespaces and continuation statements are removed for better readability of the function syntax.

if the lex parser encounters fatal errors, it will stop processing and print a list of the offending syntax.

tested under r2007a, older version 7 systems might work as well.

and the accompanying published M-file for information and a few self-explanatory examples.
