mypath.m

Displays or returns the MATLAB path, omitting directories which are inside the MATLAB "toolbox" ...

Description

Those of us who have a lot of The MathWorks' toolboxes find that every time we type "path" at the MATLAB command line, we have to scroll up several pages before we find what we're looking for.

Since most of the time we're interested in our own working directories, and since most of us don't do our work in directories under $matlabroot/toolbox, this function prints the (hopefully much shorter) list of directories which are on the MATLAB path but aren't inside $matlabroot/toolbox.

Just type:
>> mypath
to see those directories.

Alternatively, if you want to do something with the result, type:
>> p = mypath
to get the same list as a cell array of strings.

• Acknowledgements: This submission has inspired the following:; exportToZip: Identifies the dependencies of an M-file and creates a ZIP file, exporttozip
• MATLAB release: MATLAB 6.1 (R12.1)
• Other requirements: Should work in any version of MATLAB and any platform, though I have only tested on Windows and back as far as R12.1

This could be interesting but disappointingly, its not system independent. It assumes the path separator is a semicolon. Since the fix is trivial, why not make it fully flexible?

help pathsep

[Malcolm Wood]

Good point. Now uses pathsep, hopefully making it platform independent.

This looks good now. I like the use of nargout to differentiate between returning an argument and just displaying to the command window.

Minor points (that I should have caught the first time) - the help refers to USERPATH in one spot, but the function name is MYPATH. It should also document the fact that when no output argument is provided, it only displays to the command window. Otherwise a user might be confused.

This is an excellent routine to archive your work or share your work with others.

My mfiles are spread across my local hard drive and a couple of network drives. So the absolute paths and rootpath in exportToZip did not work. I created a new version "exporttozip" that uses either relative or absolute paths.

I did not know how to directly update the exportToZip file on file exchange so I submitted a new file called exporttozip. Although it is listed as my submission, Malcolm Wood should really get the credit for it.
