    I guess previous answers inverted rows and collumn, I would do:

    A=[1 2 3 ; 4 5 6 ; 5 5 5] 

A =

     1     2     3
     4     5     6
     5     5     5

    Here, the second column has the same two last elements.

    A(:,A(end,:)==A(end-1,:))=[]

A =

     1     3
     4     6
     5     5
