What format should bwboundaries take?

I have a big array of 80 by 80 0s and 1s. I am trying to feed this into bwboundaries but I am getting various errors, including 'Operands to the and && operators must be convertible to logical scalar values.' What do I need to do to solve this?

Your array does not contain only 0 and 1. Your array probably contains NaN or objects as well.

I've looked through my array and it does only contain 0s and 1s.
