"command window does not recognize the functions in editor"
There is no reason why it should: the files that are open in the MATLAB Editor can be saved in any location accesible to your OS user account, whereas the functions that can be run must be on the MATLAB Search Path or in the current directory.

I think you need to learn about the MATLAB search path.
While the editor can save a file anywhere you tell it to, when executing functions that you will create, MATLAB itself looks only in places you designate for that. Of course, it cannot search over your entire disk, as that would be far too large a place. That would make MATLAB run far too slowly. So you must tell MATLAB where to look for the files you wish to use.
The best way to do this is by using pathtool. It allows you to add a directory to your serch path. Don't forget to save the path, so the next time you open MATLAB, it will remmber that directory.
