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.

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

It is a very useful utility. Is it possible to list the actual parameters passed to each function call (not just the formal parameters used in the function definition)? Note that this may vary across calls to the same function. Thanks.

unlike FARG, M2HTML dose not
- distinguish between subfunctions and nested functions
- extract anonymous functions
- extract f/eval constructs

moreover, it is a standalone function that does not require other files and subfolders nor the web browser to display its result

just a few pedestrian thoughts...

Very pedestrian indeed: See M2HTML
