How can I find the directory containing my compiled application?

How can I find the directory containing my compiled application? The CTF data has been extracted into my user Application Data directory, but neither "ctfroot", "matlabroot" nor "pwd" show the actual location of the compiled executable.

On Windows there are two possible ways to achieve this:

Option 1:

Extract the path from the environment variable PATH, this can be achieved as in the following example:

function currentDir = getcurrentdir
if isdeployed % Stand-alone mode.
    [status, result] = system('path');
    currentDir = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));
else % MATLAB mode.
    currentDir = pwd;
end

Please note that using the function "getenv" in the above example will not work. You will have to use the "system" command to get the PATH variable that contains the path to the executable as the first entry. This entry gets added automatically at runtime by the stand-alone.

Option 2:

The alternative, on Windows as well as all other supported platforms, would be to use a MEX-file. Attached is an example that illustrates how to locate the compiled executable. To compile the MEX file, please follow the steps detailed on this page of the documentation:

On Mac machines you can use the following workaround to get the path to the directory where your application sits:

if isdeployed && ismac
    NameOfDeployedApp = 'MyDeployedApplication'; % do not include the '.app' extension
    [~, result] = system(['top -n100 -l1 | grep ' NameOfDeployedApp ' | awk ''{print $1}''']);
    result=strtrim(result);
    [status, result] = system(['ps xuwww -p ' result ' | tail -n1 | awk ''{print $NF}''']);
    if status==0
        diridx=strfind(result,[NameOfDeployedApp '.app']);
        realpwd=result(1:diridx-2);
    else
        msgbox({'realpwd not set:',result})
    end
else
    realpwd = pwd;
end

Hi Raviko

As per my understanding you want to open the excel file that has been packaged as a part of your compiled application using "deploytool".

You could navigate to the path returned by "mcrcachedir" command and then into your specific project folder. You should be able to find the extracted components of your compiled application in that location.
