How do I tell which toolboxes my program uses?

Does anyone know of a quick way to test which toolboxes are used in a set of code. I have a large project (spread accross different functions), and I can't remember what toolboxes I had available when I wrote it.
I only have the basic install of MATLAB at my new company and need to figure out which toolboxes to buy. I can identify one because the code crashes when it hits a particular function, but can't easiy find out if there are others.
Perhaps there is a script out there to search the text and compare it against a list of functions in the different toolboxes?

Does your code have any instances in which the name of the function was given as a string, such as a callback specified as a string, or instances of eval() or evalin() ?

There are a couple of things to try and consider. First, you can run code on a machine that has the necessary products (e.g. a trial version) and after running the code execute:
license('inuse')
and it will return what products you have used. With the exception of the point Walter mentione in his comment (in case the code uses EVAL), this is a save method.
Then there is the DEPFUN command that lists dependencies. I have seen users work with that, but you need to have a good understanding of the function names and to which product they belong. You may need to do research and it is error-prone.

Wouldn't "licence inuse" catch calls to EVAL as well? EVAL operations would also check out the appropriate license, so it should be pretty robust.

matlab.codetools.requiredFilesAndProducts will list all the toolboxes used in the m script.
Check this documentation link : http://in.mathworks.com/help/matlab/ref/matlab.codetools.requiredfilesandproducts.html

@Evan
Set the random number generator to swb2712 and generate two random numbers. Multiply each of them by (-1)^randi(2) * 2.^randi([0 1024]) . complex() the two parts together. If I have constructed the numbers correctly, the complex number that results should potentially include every normalized complex number except for the ones with component 0 -- though I might be overlooking a boundary condition on the upper end. swb2712 generates every representable number on the open interval (0,1)
Okay, now have the code do
if x is a zero of the zeta function and ...
x is not a negative integer and ...
x is not a positive integer plus 1i/2
call a function in the Control System Toolbox
else
call a function in the Signal Processing Toolbox
end
Question for you:
Is it possible for MATLAB to tell you which toolboxes the function calls?
No, the answer is not "Control System Toolbox and Signal Processing Toolbox". It only calls one toolbox on any run. Is it possible to show that sometimes it will call one and sometimes it will call the other?
In order to show that sometimes it will call one toolbox and sometimes it will call the other toolbox, the examing program would have to come up with a proof or disproof of the Riemann Hypothesis . Which is something that no-one has been able to do in the last century.

I suspect you could work up a variation on Turing's Halting Problem to show that there are deterministic programs where you cannot possibly tell in a finite amount of time which toolboxes the code invokes.

You could do a dependency report for each folder that your code is in (from the menu in the Current Folder window). The toolboxes will be apparent from the locations of the functions.

There is also a very useful submission by Us FDEP: function dependencies finder which detects calls to evalin also.

Calling

   fdep('functionName','-l')

shows the dependencies in a GUI (here's just a preview):
