e = 1.0000e+100

3   Pass
x = [1; 2]; y_correct = []; assert(isequal(common_by_row(x),y_correct))

4   Pass
x = ones(10); y_correct = [1]; assert(isequal(common_by_row(x),y_correct))

e = 1 e = 1 e = 1 e = 1 e = 1 e = 1 e = 1 e = 1 e = 1

5   Pass
x = magic(10); y_correct = []; assert(isequal(common_by_row(x),y_correct))

6   Pass
x = wilkinson(9); y_correct = [0 1]; assert(isequal(common_by_row(x),y_correct))
