You set it up in the function call. For example, here's the first line of a
function

function [A,f,tt] = hhspectrum(imf,t,l,aff)

And here is the line that gets the values A,f,tt back to the calling program

[A,f,tt] = hhspectrum(imf,t,l,0);

In the calling program, you could change the names to be different from
those in the function, if desired, e. g.,

[B,g,ttt] = hhspectrum(imf2,tx,m,0);

It's the position in the list that matters, not the actual variable name.
