Passing Functions and m-files to functions

Hi Mathworks,
I have an m-file which codes up a system of differential equations;
9D_system
This has various parameters in it, and I have a few parameter schemes for specifying the values to these parameters;
P1.m, P2.m, P3.m
I want to be able to specify which parameter scheme I endow the system with, and then solve this system of differential equations with ode15s.
How do I do this?
Moreover, the parameter schemes
P1.m, P2.m, P3.m
each call functions (some of the parameters are functions of other parameters, and so must be calculated by these called functions). Thus the ode will have a series of nested functions being called!!
Any help on this would be greatly appreciated. :)

@Linford, these are the ways we recommend passing extra parameters:
e.g:
ode45(@(t,y)myfun(t,y,@p1)
And
function x = myfun(t,y,pfun)
stuff = pfun();
x = do_things_with(stuff,t,y)

Or add the parameters as additional arguments to the anoymous function directly. See also: http://www.mathworks.de/matlabcentral/answers/1971

myStr = 'P1.m'
function [result] = myFun(someArg, myStr)
[str str] = fileparts(myStr);
run(str); %calling your script
