Test Status Code Input and Output
1   Fail

Output argument "y" (and maybe others) not assigned during call to "longnan". Error in Test1 (line 11) assert(isequal(longnan(x),y_correct));

2   Fail
x = eye(3); y_correct = [0 0 0]; assert(isequal(longnan(x),y_correct));

Output argument "y" (and maybe others) not assigned during call to "longnan". Error in Test2 (line 3) assert(isequal(longnan(x),y_correct));

3   Fail
x = eye(3); x(1,1) = nan; y_correct = [1 0 0]; assert(isequal(longnan(x),y_correct));

Output argument "y" (and maybe others) not assigned during call to "longnan". Error in Test3 (line 4) assert(isequal(longnan(x),y_correct));

4   Fail

Output argument "y" (and maybe others) not assigned during call to "longnan". Error in Test4 (line 9) assert(isequal(longnan(x),y_correct));

5   Fail
x = nan(10); y_correct = repmat(10,1,10); assert(isequal(longnan(x),y_correct));

Output argument "y" (and maybe others) not assigned during call to "longnan". Error in Test5 (line 3) assert(isequal(longnan(x),y_correct));
