Recall a sub function with multiple outputs?

I am writing a code to calculate a decay rate. In one of the sub functions, I wrote:

[x, iter] = bis (a,b,tol,L)

so when I use this sub function in my code, for instance:

k = bis (a,b,tol,L)

i will get a "k", but what exactly is k? And if I only want k = iter.. what should I write in my code so that k = iter?

If you only want the 2nd output, write this

[~,k] = bis (a,b,tol,L)

That little tilde (~) is effectively ignoring that first output, in the calling function.
