MATLAB: Using dir() without changing directory

cddir

I need to find files that have dir(['*K1*.json']); in their names which are in a specific folder different from the matlab script folder. I prefere not to change directory because I will get error while running the script.

Is there any way to do so?

Use an absolute path rather than a relative path (as proposed in the comments). It's easier to get it right. Thus try

sad = dir( fullfile( 'c:', 'specific', 'folder',  ['*K1*.json'] )  );

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.
