Test Status Code Input and Output
1   Fail
A = [ 1 5 8 -3 NaN 14 0 6 NaN ]; B_correct = [ 1 5 8 ]; assert(isequal(remove_nan_rows(A),B_correct))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in remove_nan_rows (line 2) B = A(sum(A,2~=NaN),:); Error in Test1 (line 5) assert(isequal(remove_nan_rows(A),B_correct))

2   Fail
A = 1:10; B_correct = A; assert(isequal(remove_nan_rows(A),B_correct))

Index in position 1 exceeds array bounds (must not exceed 1). Error in remove_nan_rows (line 2) B = A(sum(A,2~=NaN),:); Error in Test2 (line 3) assert(isequal(remove_nan_rows(A),B_correct))

3   Fail
A = [ 1 5 8 -3 NaN 14 0 6 6]; B_correct = [1 5 8; 0 6 6]; assert(isequal(remove_nan_rows(A),B_correct))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in remove_nan_rows (line 2) B = A(sum(A,2~=NaN),:); Error in Test3 (line 6) assert(isequal(remove_nan_rows(A),B_correct))

4   Fail
A = [ 1 3 6 NaN 3 NaN]'; B_correct = [1 3 6 3]'; assert(isequal(remove_nan_rows(A),B_correct))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in remove_nan_rows (line 2) B = A(sum(A,2~=NaN),:); Error in Test4 (line 3) assert(isequal(remove_nan_rows(A),B_correct))

5   Fail
A = [ 1 3 6 NaN; 3 4 2 1]; B_correct = [3 4 2 1]; assert(isequal(remove_nan_rows(A),B_correct))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in remove_nan_rows (line 2) B = A(sum(A,2~=NaN),:); Error in Test5 (line 4) assert(isequal(remove_nan_rows(A),B_correct))
