Details:

The documentation of tril says:


If the value of @var{k} is negative, additional elements above (for\n\
@code{tril}) or below (for @code{triu}) the main diagonal are also\n\
selected.\n\


However, in fact we need a positive value of k to make elements above the main
diagonal also selected for tril. If the value of k is negative, less elements
are selected.
