How can I call one of the outputs of a function in another script and plot it?

Hi.
I have a function:
----------------------------
function F = tethsolve3(p,H,L);
x0=[2;2];
g=9.82;
mu=0.0141*g;
% [x,fval]=fsolve(@Teth3,x0);
[x,fval] = fsolve(@(x) Teth3(x, p, H, L), x0);
Th2Radian=atan(sinh((x(1)+p)*mu/x(2)));
T2=x(2)/cos(Th2Radian)
end
-------------------------------
I need to plot one of the outputs of the function in another script for different inputs, as follows:
------------------- L=108;
H=100;
g=9.82;
mu=0.0141*g;
for p=0.01:1:10;);
tethsolve3(p,H,L);
T2=T2
p=p
plot(p,T2)
hold on
grid on
end -------------------------------
But there is an error. I guess it's because T2 is not really an output. Do I need to use a function handle???!
Please advise.
Thanks a lot.

No, you need to return back to the caller any outputs from your function(s) that you need to have for further use--functions, otherwise, are pretty much useless for computations.
You wrote
function F = tethsolve3(p,H,L);
but F isn't ever defined so the end result of calling tethsolve3 is--well, nothing.
