Thread Subject: editing/using mfile from Toolbox without admin rights (n00b)

I have a total n00b question. I spend hours looking in the
Help-functions but it drives me crazy. Each time when I think I found
the solution it didnt help. I hope you guys can help me out. The
solution is probably very simple, yet, I didnt found it.

For my graduation project I need to change a mfile from the Toolbox.
The problem is that I cannot save it in the current directory because
it is public school PC Im working on. I have tried to save it in my
own directory but then I get errors that Matlab cannot specify a
function. The message is:

Undefined command/function 'findpeak'.

Error in ==> cpcorr at 115
    [xpeak, ypeak, amplitude] = findpeak(norm_cross_corr,subpixel);

The problem is probably that I use some mfiles from my own directory
(USB hdd) in combination with the mfiles from the Toolbox.

However, I hope you can help me out. I think the solution is very
easy, and just the settings I have to edit (I hope).

As long as your functions are well-defined and visible on your path, you
should be okay. See "help path" and "help which" for help.

Hi,

The problem is that 'findpeak' is a private function, it can be
accessed only by functions which are located in the directory just on
top.
So I'm afraid that you have to copy it and all other private
functions your function need in your own directory.
I suppose that the problem will arise if the function uses some
classes which are located in the original directory.

I was also thinking about that. Do you know how I can find out (as
quickly as possible) which private functions I have to copy-paste to
my own custom directory? Is there a command for it?

Thanks for the replies

Hi,
You can try the function depfun.
I've never used it, and I'm not sure that it take the private
functions but it's the only way I see.
