How does a MATLAB generated binary knows its fullpath?

I have a MATLAB compiler generated binary (exe/jar/dll).

I would like to be able to get the full path of the binary itself at runtime.

Any ideas? Help will be very appreciated.

See ctfroot()

ctfroot returns the location of ctf. What I want is the location of binary, not where it is deployed.

   [~, result] = system('path');
   currentDir = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));

is what we have in our repo under a function claiming to get the executable directory when in deployed mode. Even though I wrote this function I am 99% sure I got this solution either from Matlab Answers or somewhere else online though so if it works I take no credit and if it doesn't then I can't really help answer any questions on it as a solution!

[Hanan Kavitz]

Yes, I'm familiar with this solution and using it elsewhere.

This will work great for exe but will it work for jar or dll?

I don't think so as their location isn't automatically added to the beginning of the process path. Am I wrong here?

I can't remember off the top of my head exactly where ctfroot points to, but dlls that are packaged with your executable are copied to a location under there so far as I can see. In my case the dlls are in a relative location under there identical to where they are in my undeployed code relative to my root folder.

I use the above solution for a pdf manual that we package up too, but that is added in the 'File installed for your end user' section which is where the above solution points to.
