Since some of the m-files I work with are very large, and contain many nested functions and subfunctions, I find it helpful to keep a short and simple table of contents in the top comment block that tells me which functions are in the m-file, their line numbers, and how they are nested. I wrote FTOC to generate this function table of contents automatically. This was inspired by a posting by Yair Altman on the mathworks newsgroup where he described how to use the undocumented function MLINTMEX. If you're interested in getting even greater detail about m-file contents, you should check out the postings by Urs Schwarz acknowledged below.
Here's how FTOC is used:
STR = FTOC(FILE) returns a character array table of contents STR for all nested functions and subfunctions within the m-file FILE (built-in functions are not displayed). The line numbers of each function are included, and the indentation of the function names indicates the nesting order. FILE should be an m-file name. If FILE is not found, or there are no subfunctions or nested functions, STR will be an empty string.
STR = FTOC(FILE,'insert') will return a character array table of contents STR formatted for the purpose of inserting it into the header comment block of the m-file FILE. Each line begins with the character '%' and the line numbers are adjusted to account for the fact that STR will be inserted somewhere within the top comment block of FILE. (NOTE: you will want to first remove any old table of contents from the comment block before pasting the new one in, to make sure the line numbers are adjusted correctly.)
