Put your data into two columns of the same array. If your data are not of
the same length it's a little more complicated, but not much.

Can someone help me out here? This is one of those areas of C

If you could provide an example, that would help out a lot.
I know it has to do with the expectation that the variable can be
changed outside of the control of the program. I know it has to
do with telling the compiler to not optimize that piece of code,
so that the variable can be changed from outside of the program.

Phone:804-271-...Calling functions from functions from functions ...
Lets say I have a function g(p,x) where x and p are of some defined type.
I also have a function NewtonR which I can use like so:
x = NewtonR(g,p,x0)
There is also another function I want to call ImplicitTrap which can be
u = ImplicitTrap(g,p,u0,step,n)
This function defines a function of g, and it is this function that I'd
like to pass to NewtonR. Can it be done?

automatic differentiation being used to handle the differentiation. M...Random Functionality
I want to create a script that has random functionality.
I want the script to randomly choose between an unknown number of
subroutines and run one of them. By "unknown" I mean that the neither
names of the subroutines, the references to the subroutines, nor the
number of subroutines are hard coded into the script, but are determined
at runtime. This will allow me to add additional functions to the list
of possible random functions without having to update any other portion
of the script.
If that is as clear as mud, the code sample below demonstrates what I
want to do.
