MATLAB: Get full path of directory that is on Matlab search path

what command

Hello,

I have a folder called 'mydir' that is in the Matlab search path but not in my current directory. Thus isdir('mydir') is true. Is there a way to easily extract the full path of 'mydir' in this scenario?

Thanks, Justin

One way

>> s = what('InUse');
>> s.path
ans =
h:\m\FEX\InUse

where InUse is a folder on my Matlab path

MATLAB: Looking within search path for a directory containing a chosen string

Probably not a whole lot unless...

IF the subdirectories were to be on a given higher level path branch, then one could probably get the desired result directly via a shell dir() command with the suitable wild card. Would depend on the shell for specific switches, of course, as well as the above condition. On Winders CMD.EXE, the following seems to work...

[~,dirs]=dos(['dir /s /a:d /b *' strToFind '*'];

Whether it would be faster/better would likely be in the eye of the beholder and how high up in a location would have to be to cover the whole chain desired. Of course, one will need to ensure the starting path is where it needs must be in the running shell so likely need to create a batch file that takes care of that detail and dispatch it instead...

I haven't ever understood why there isn't an extension to a cellstr of strfind that "just works"; doesn't seem that big a deal.

MATLAB: Is MATLAB 7.0.4 (R14SP2) unable to recognize the files, when I use the COPYFILE command in the script

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

This has been verified as a bug in MATLAB 7.0.4(R14SP2) in the way COPYFILE notifies MATLAB about the changes made to a destination directory.

The followings are some workarounds to resolve the issue:

1. Using an absolute path name:

Use an absolute path name as an input to functions(TYPE in this case) accessing the destination directory as follows:

FullPathTempDir = tempname; 
[temp_dir temp_file] = fileparts(FullPathTempDir); 
mkdir(FullPathTempDir); 
destinationFile = [temp_file,'.m']; 
origPath = addpath(FullPathTempDir); 
copyfile('hSampleDisp.m',fullfile(FullPathTempDir,destinationFile)); 
type(fullfile(FullPathTempDir,destinationFile));

2. Use WHICH or EXIST on the path of the destination directory as follows:

FullPathTempDir = tempname; 
[temp_dir temp_file] = fileparts(FullPathTempDir); 
mkdir(FullPathTempDir); 
destinationFile = [temp_file,'.m']; 
origPath = addpath(FullPathTempDir); 
copyfile('hSampleDisp.m',fullfile(FullPathTempDir,destinationFile)); 
which temp_file
type(temp_file);

3. CD to the directory, in which the file is located, before accessing the file.
