Details:
Test Case:
>> c = [1 1.5 -1 0.2 2; 2 1.8 1.2 0.4 -0.8;1.6 NaN 0.7 2 -2;-1.1 1.5 0.1 -0.7
0];
>> surf(zeros(size(c)),c)
Produces matlab_surf_nan_bug.png in matlab and octave_surf_nan_bug.png in
octave.
Using
>>surf(zeros(size(c))+(c-c),c)
in Octave (So there is a NaN in the zeroes matrix to match the one in the
colour matrix) produces octave_surf_bug_2.png. Looks like there's some
difference in the averaging to me.
