Any version of "empty" should be acceptable as correct.
For example, intersect can output a 1x0 empty matrix. That should be allowed.
Somehow the assert is triggered if the function returns a [] that has been "sorted".
If I include that code
if ~isempty(y)
y = sort(unique(y));
end
no assert is triggered. Seem strange!
How can the leading solution be 0??
Following many comments, the Test Suite should be amended to check for an empty output vector using "isempty", rather testing for equality to []. Such an amendment is appropriate, and would not break any of the previously submitted successful solutions. —DIV
Test cases with an empty result now test against isempty().
