Test Status Code Input and Output
1   Pass
x = []; y_correct = []; assert(isempty(common_by_row(x)))

y = 0×1 empty double column vector

2   Pass
x = [1e100; 1e100]; y_correct = [1e100]; assert(isequal(common_by_row(x),y_correct))

y = 1.0000e+100

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

y = 0×1 empty double column vector

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

y = 1

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

y = 0×1 empty double column vector

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

y = 0 1

7   Pass
x = [3 -2 1 NaN; NaN 0 -2 3]; y_correct = [-2 3]; assert(isequal(common_by_row(x),y_correct))

y = -2 3
