All files added with the -a option are then placed in the directory ./exe_mcr/ . If I however include the CTF archive in the executable (no separate .ctf file), the executable can't seem to find the data files. I know they are included in the executable, since its size has grown to the expected size. Is there a special directory to use, or is something else the problem? Thanx in advance!

I know this is old, but in case it's still unsolved...

If it's just a data file that you want the contents of, you can read the contents like this:

data = fileread('mydatafile.txt');

If you've imbedded something you want to be available to run outside matlab, you need to write it out to file. I did this with an executable which I included with -a.

% Read the data & write it out to file:
fcontent = fileread('myfile.exe'); % Read file contents from ctf archive
fid = fopen([pwd filesep 'outfile.exe'],'w','n'); % Create new file in current directory
fwrite([pwd filesep 'outfile.exe'],fcontent,'char'); % Pass file contents through
fclose(fid); % close file

% Open the file from the working directory with the SYSTEM command
[status, result] = system([pwd filesep 'outfile.exe']);

Hope this helps.

Correction, I made a hasty paste and got the fwrite call wrong. That code block should read:

% Read the data & write it out to file:
fcontent = fileread('myfile.exe'); % Read file contents from ctf archive
fid = fopen([pwd filesep 'outfile.exe'],'w','n'); % Create new file in current directory
fwrite(fid,fcontent,'char'); % Pass file contents through
fclose(fid); % close file
