Using "or" operands when indexing a matrix

Hi all,
I am trying to speed up a for loop that I have by using indexing instead of "if" statements. To that end I have the following line of code:
idx = find ((MouseData(k).BehaviourData(:,4) == NovMouse) || (MouseData(k).BehaviourData(:,5) == NovMouse) || (MouseData(k).BehaviourData(:,6) == NovMouse));
However when I run it, I get the following error:
Operands to the || and && operators must be convertible to logical scalar values.
It is worthy of noting that NovMouse is a scalar value, as is MouseData(k).BehaviourData(:,4).
Alternatively, I would appreciate any alternatives to this code that wouldn't take too long run.

If operands are arrays then use single (|) instead of (||)
idx = find ((MouseData(k).BehaviourData(:,4) == NovMouse) | (MouseData(k).BehaviourData(:,5) == NovMouse) | (MouseData(k).BehaviourData(:,6) == NovMouse));
