Non-scalars are not supported in IF or WHILE statements

if true
  [min_bb,idxb]=min(errorb(:,:,ii));
[linebb,codexbb]=ind2sub(size(errorb),idxb); %find minumum location per_phase
end

this my code, I am trying to use "codexbb" and "linebb" in IF statement like

if(linebb==2)

but, matlab gives an erros and said "Non-scalars are not supported in IF or WHILE statements". On the other way, when I checked its dimensions, it says 1 1. How can I solve the problem ?

linebb is a vector, what do you want to test? for example if

linebb=[1 2 3]

your are trying to compare linebb to 2,

linebb==2

the result is

0 1 0

you have to explain what you want, if you want to test if 2 belong to linebb you can do it by

ismember(2,linebb)

Can you post the code with your if statement?
