I have 2 columns, filled with scalars 0 or 1. I would like matlab to find all the 1's that are in the same place in one column as in the other, and the same thing for the 0's. How am I supposed to go about this? Any help would be greatly appreciated!

So, you want to find all rows that are 11, and 00? If so, I suggest using intersect.

Not the right way but gets the job done, assuming the vectors are A and B

ANSWER = ((A+B) == 2) + ((A+B) == 0)

the brackets are really important , now in answer the 1s are corresponding to the indices where both A and B match
