How can I get a value from another m file ?

Hi , Lets say I have the following m file

function y = f1(x)
y = exp(x);
title = 'graph 1';
end

how can I access the variable (title) in my main m file ? for example using the title for a plot in my main file

nero - return title as an output parameter from your call to the function

 function [y,title] = f1(x)

Although, would the title always be 'graph 1', or could it be something different?

and how would I call it in my other m file ?

because im getting the following error

Undefined function or variable 't'.

Error in test (line 18)
        value=t

where test is my main function and I did what you suggested ( function [y,t] = f1(x) ) but I changed title in to t

[Geoff Hayes]

In your main m file, you would call the function as

 [y,t] = f1(x);

passing your x into this function and obtaining the output parameters y and t (the title). How are you attempting to call the function now?
