If you have a complex set of functions that are synced over different systems (or run from a USB) it can still be necessary to interact with subfolders. This function implements one of several options to find the full path of the calling function, so you can still create/load files in subfolders not on the Matlab path.
Tested to work on Matlab and Octave. This code should be OS-independent and release-independent.
(I personally use this as a subfunction of a function that returns several folder names. The goal of that file is to allow me to move around folders, without having to check all my code to see if anything breaks.)
Update to v1.1:
Returns the current working directory as output when called from the command window or 'run section' (instead of returning an error).
