## Test ordering of complex values by magnitude and then by phase
%!test
%! x = [0 i 1+i 2 3i 3+4i];
%! assert (sort (x, "descend"), fliplr (x));

%!test
%! x = [1, -1, i, -i];
%! xs = [-i, 1, i, -1];
%! assert (sort (x), xs);
%! assert (sort (x, "descend"), fliplr (xs));

## bug #44071, issorted incorrect because it uses different sort routine.
%!assert (issorted ([1, -1, i, -i]), false)

## bug #43313, -1 is both '>' and '==' to (-1 - 0i)
%!test
%! assert (complex(-1,0) == complex(-1,-0), true);
%! assert (complex(-1,0) > complex(-1,-0), false);
%! assert (complex(-1,0) < complex(-1,-0), false);

## Test that sort and issorted both agree on boundary case
%!test
%! x = [complex(-1,0), complex(-1,-0), i, -i, 1];
%! xs = sort (x);
%! assert (issorted (xs));
