Thread Subject: How can an m-file get its path?

..Put another way, can you write function 'where_am_i'
that, when run, would tell you in what directory it
resides? (No, 'cd' or 'pwd' won't work).

Thanks a lot!

Hi
If I had understood the question...
When you are in the function you can access to its full name
with mfilename so also to its directory :
p = mfilename('fullpath') %gives the fullname
fileDirectory = fileparts(p) %gives the directory of the
current running m-file

p = mfilename('fullpath') returns the full path and name of the M-file in
which the call occurs, not including the filename extension.

Perhaps something involving WHICH. That will work
if your function is on the path and it is the only function
(or the first in precedence) by that name on the path.

Ah! Found your answer while investigating the HELP
for another useful function, INPUTNAME.

The function you want is MFILENAME:

P = mfilename('fullpath');

Problem solved, thanks to everyone who responded!

Others have pointed you (rightfully!) to MFILENAME. I just
wanted to suggest that DBSTACK may also be useful,
especially in subfunctions.
