[Octave-bug-tracker] [bug #50466] makehgtform function missing

[Peter Corke]

Follow-up Comment #15, bug #50466 (project octave):

Here's the minimalist example

octave:8> hg=hgtransformhg = -27.983
octave:9> plot3([0 0 0; 1 0 0], [0 0 0; 0 1 0], [0 0 0; 0 0 1], 'parent', hg)

% the 3D plot is drawn perfectly
% now I apply  a rotation of pi/2 about the x-axis

octave:10> T=[1   0   0   0; 0   0  -1   0; 0   1   0   0; 0   0   0   1]
T =

   1   0   0   0
   0   0  -1   0
   0   1   0   0
   0   0   0   1

octave:11> set(hg, 'Matrix', T)

and the result is not correct, the lines are no longer orthogonal.
