Hello. When i try to run a .bat file from matlab, an error appears in a cmd window: "terminate called after throwing an instance of 'std::logic_error' what(): Could not find user home direct" What should I do to correct this ? PS: when I run it from the cmd window, every thing works correctly. Thanks for your help.

How are you running said file?

Are you using a system() call?

Yes I tried this way, but I also try to use this little program:

batFile = 'c:\name_folder\name_file.bat';
startInfo = System.Diagnostics.ProcessStartInfo('cmd.exe', sprintf('/c "%s"', batFile));
proc = System.Diagnostics.Process.Start(startInfo);
if isempty(proc)
    error('Failed to launch process');
end
while true
    if proc.HasExited
        fprintf('\nProcess exited with status %d\n', proc.ExitCode);
        break
    end
    fprintf('.');
    pause(.1);
end

I think the problem comes from the way that matlab is using "cmd", maybe I don't have all the right, or something like that... Maybe their is some thing to change in "startInfo" but I don't know what :)
