It seems to compare with 0 as I do above. For example, the following 2 tests work in matlab 2011b tmp=ones([2,3,4]);tmp(2,2,2)=.3;isequal(bwlabeln(tmp),ones(size(tmp))) tmp=randn([2,3,4]);isequal(bwlabeln(tmp),tmp~=0) Kris ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
