Hi, 

Octave patch does not plot line defined by two points.  Octave does not draw
the patch and does not return an error.  The plot is silently empty. Thanks. 

Replacing a single patch with a for-loop with many individual line commands is
very slow, as you would expect.

% example

pts=[0 0 0;1 1 1]; tri=[1 2]
figure; patch('Vertices', pts,'Faces', tri, 'EdgeColor', 'k');
