Details:



[X, Y] = meshgrid (linspace (-3, 3, 40));
Z = sqrt (abs (X .* Y)) ./ (1 + X.^2 + Y.^2);
A = meshc (X, Y, Z, 'FaceColor', 'r');


Matlab it plots as expected, and checking the underlying surface object:


>> A(1).FaceColor
ans =
     1     0     0


in Octave, the plot is produced and matches the matlab output, but the
following error is received and the handle A is never created:


>> A =  meshc (X, Y, Z, 'FaceColor', 'r');
error: set: unknown hggroup property FaceColor
error: called from
    __contour__ at line 233 column 8
    meshc at line 101 column 16
>> A
error: 'A' undefined near line 1, column 1
