Hi,
How do I actually save variables that are in a function file?

You cannot do this without altering the function file (or at least one function or script that it calls directly.)
You can, as Titus indicates, use assignin() in the function file. Better, though, would be to return the variables from the function and do the assignment outside of the function.

Seconded. Using assignin completely destroys any readability or tracibility of your code. Magicking variables into existence is not recommended. Returning the values as outputs from the function is much clearer and safer.

Of course. The original question did not make me think about what the OP really might have wanted to do ...

Use the function save? ;-)

Yes. You can either load them in the base workspace later or use assignin, if you want to bring variables from your function to the base workspace directly.

You can save in two different ways:
- Assign the output variables, e.g.: function [Out1, Out2, Out3, Outn] = MYfunction(In1, In2, In3, InN)
function [Out1, Out2, Out3, Outn] = MYfunction(In1, In2, In3, InN)
% that saves the outputs Out1, Out2, Out3, Out4 when you recall and execute the function file called: MYfunction.
Out1 = In1+In2;
Out2 = In3/In1;
Out3 = In1/In2;
OutN = InN/(In1+In2+In3);
end
2. Use and set up: assignin() % Not recommended for a few good reasons
e.g.: assignin('base','Output1', Out1)
