Let's say I have a set of numbers A=-5,-4,-3,-2,-1,0,1,2,3,4,5
and I want to pick those pairs that give a sum of 1. For example, -2 and 3 is one possible pair, but how do we display all such pairs?
Any help will be much appreciated.

A=[-5,-4,-3,-2,-1,0,1,2,3,4,5];
index=(A+A')==1;
[I,J]=find(index);
A([I,J])
