hi, I have two matrices with 20 rows and 4 columns and I want to compare them using ismember. my problem is that i want to consider every row as a single input as if my matrices are 20x1 vectors.
how can i do that?

ismember(A, B, 'rows')
% Or maybe
ismember(A.', B.', 'rows')

nextEq = ~any(diff(A, 1, 1), 2)
diff() subtracts elements of an array along the dimension specified as 3rd input argument. any(X, 2) checks if any element along the 2nd dimension differs from zero.
