e.g. I have a function [A, B, C] = foo(vargin). Now I ONLY want the second return value B. Is there any way to get only B without keeping A and C in place or modifying my function code.

The best way is this: [~, B] = foo(vargin). Works since Matlab 2009b I think

You type quicker than me :-) – am304 Jul 23 '13 at 14:27

2@am304 That's because you wasted precious time typing that extraneous second `~` ;) but +1 for you anyway – Dan Jul 23 '13 at 14:28

Oh, come on. It is NOT that messy. In fact, there are several ways to do this trivially even without the ~. – Jul 23 '13 at 14:54

@woodchips I'll remove that sentence if it upsets you. Perhaps you can post the alternatives? – Dan Jul 23 '13 at 14:55

[~,B,~] = foo(vargin)
I think it doesn't work in older versions of MATLAB, but can't remember for sure when ~ was introduced.
