matlab - How do I get the second return value from a function without using temporary variables?

I have a function that returns two values, like so:

[a b] = myfunc(x)

Is there a way to get the second return value without using a temporary variable, and without altering the function?

What I'm looking for is something like this:

abs(secondreturnvalue(myfunc(x)))

not that i know of. subsref doesn't seem to work in this case, possibly because the second variable isn't even returned from the function.

since matlab 2009b it is possible to use the notation

[~, b] = function(x) 

if you don't need the first argument, but this still uses a temporary variable for b.
