editall

Opens all M-files in directory for editing.

Description

editall(dir) opens all M-files in directory dir for editing. If dir is not specified, all M-files in the current directory are opened. I often use this when working on large projects over a period of time. It is useful to issue one command each time I start Matlab that will open all the M-files I am working on. I put this file in ~\MATLAB\R2006a\toolbox\local so that I can call it from whatever directory I am working in currently.

I was informed that this was not working properly in r2007 when placed in the local toolbox. I do not understand this, and would love to have someone explain why! I altered the code so that it should work for both versions. It may take a day to show up. Thanks.

Matt,

Its usually recommended not to put your own files in the toolbox directories. These directories are cached by Matlab at startup, so if you put a function there, Matlab will not "see" it until the next time you start it up. And any modifications to your function will not be recognized.

Instead, put all of your own functions in a separate directory (or directories) that are placed on the search path. The save the search path, so that matlab will always find your functions when you start up again.

Thanks John,
I was aware of the caching issue, so I always rehash when I alter a file in toolbox. I think I may have an idea of what happened now in my case. It seems that the computer I wrote this one uses xp (and R2006a) and the one I used it with last night has Vista (and R2007a). Vista has a weird thing where it won't let you write to folders or files in 'Program Files', and instead writes to a 'virtual store' and I think this was messing up Matlab somehow. So I was thinking it was a Matlab version conflict, but it was Microsoft, which I guess shouldn't be surprising. Thanks again.
