Test Suite

Test Status Code Input and Output
1   Fail
x = []; y_correct = []; assert(isequal(common_by_row(x),y_correct))

Index in position 1 exceeds array bounds. Error in common_by_row (line 2) y = x(1,:); Error in Test1 (line 3) assert(isequal(common_by_row(x),y_correct))

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

y = 1.0000e+100

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

y = 1×0 empty double row vector

Assertion failed.

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

y = 1

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

y = 1×0 empty double row vector

Assertion failed.

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
