Hi, 

I got an error for the example below. If the patch is replaced with a fill3,
no error is issued. Thanks.    

P0=[6  3 -4 
    0 -2 -4
    0 -6  6 
    6 -6  3]; 


% with patch 

figure; ax2=axes;
patch(ax2,P0(:,1), P0(:,2), P0(:,3), 'r'); 
hold on; xlabel('x'); ylabel('y');  
campos, campos(campos-1e-12); campos
 
error: set: "cameraviewangle" must be finite
error: called from
    campos at line 104 column 8
 
% no patch, no error message 

figure; ax2=axes;
fill3(ax2,P0(:,1), P0(:,2), P0(:,3), 'r'); 
hold on; xlabel('x'); ylabel('y');  
campos, campos(campos-1e-12); campos
