derivitive matlab temp function

in matlab how would I ask the user to enter a starting guess V0 to use as the first value for the Newton-Raphson method. If this guess causes the derivative of the temperature function to be zero , the method will immediately fail due to a division by zero. Che

You require an additional input to your function.
function y = fun(v,v0)
%The Newton Raphson Method
...
%check condition for division by 0
if statement == 0
error('Division by 0 detected, stopping the function');
end
% continue the method
...
end
What exactly is the problem you are running into?
I don't know if I should write a user defined function or write the code directly into my script file

Both would work fine. script would be easier IMO. You can also find some example functions in the fileexchange
