I'd like to be able to change my PATH variable between two different values easily without manually adding and removing paths from the PATH variable for Matlab. I have a usual setup with the PATH variable set to include all the default Matlab paths plus my little repository of custom functions I keep on my computer. I'm readying a project that will distribute some code and I'd like to make sure the scripts and functions I distribute are complete and don't depend on some script that's on my desktop's normal PATH. I created a folder called 'project' and put each of the final edits of the scripts and functions as I make them. It would be nice if I could flip a setting and my PATH changed to only the default Matlab paths plus the 'project' folders without manually removing my normal paths and then revert to my normal paths when I'm not working on the project. That way, if I call a function that I haven't edited and put into place in 'project', it won't run any scripts/functions in my normal PATh and I'll get the appropriate error to alert me that I still need to put that script/function in the 'project' folders.
Is there an easy way to do this without manually editing the PATH variable?
