current directory on startup

If you have a Matlab exe that needs to read a txt file located in the same directory as the exe but you don't have aprori knowledge of the directory name. And when you start the Matlab exe in C:\blah\blah\whatever directory

it looks in win\system32 for the text file.

Is there some generic default $CURRENT you can use in the Matlab code to cd($CURRENT) to force the exe to always look in the directory that it is located in to find the file?

You could always have a startup.m that cd() to the folder you want at startup.

doc startup
doc cd

Not sure is this is what you're looking for.

Could use you "matlabroot" to determine the directory of the .exe and then fullfile and cd to get where you wanted to go? There's an example on the matlabroot doc page:

Thanks for the reply...

It is close. If I knew the directory the exe and txt were copied into. However all I know is that they will always be in the same directory. So I need the exe to look in its location for the file.

If you are using a deployed application, you might also find value in the ctfroot:
