Finding the full path of an opened file
in [Matlab]
|
From: Jon Harris on 23 Mar 2010 15:19 In a .m script, I've opened a file with fopen. Since Matlab has various path search options, I'm not sure where the file was actually opened/created. Is there a way to find the absolute path of the file? The file may have been specified with just a simple filename (test.txt), a relative path (..\test.txt), or an absolute path and filename (C:\test.txt). I want a way to find out the full absolute path. I'm on Windows if that makes a difference.

I ask this question while ago and I come to the conclusion is the best way is: file='..\test.txt' fullpath=cd(cd(fileparts(file))) Bruno

But if the file is just a name, I get this: » file='test.txt' file = test.txt » fullpath=cd(cd(fileparts(file))) ??? Name is nonexistent or not a directory
