MATLAB: Finding row entries that are not equal

finite elementsMATLAB

Hello everyone,
I have a matrix and I would like to find all of the rows such that the entry in the first column does not match the entry of the second column.
Background: I am running some finite element code. I am finding all entries of the stiffness matrix that are positive, but in particular I want to find the stiffness matrix off-diagonal entries that are positive.
Thank you in advanced!
Andrew
