MTEX Poles Figures MTEX Erreur

Hello,

I 'am trying to plot poles figures for my EBSD data with MTEX a MATLAB toolbox

I am trying that by the code below

%% Plot poles Figures

% the selected crystal directions

h = Miller({1,0,0},{1,1,0},{1,1,1},MB_EBSD.CS);

% plot their positions with respect to specimen coordinates

plotPDF(MB_EBSD.orientations,h, 'antipodal', 'contourf', 0:1:10.0, 'minmax', 'colorRange',[0,10]);

mtexColorbar

I get this erreur, could anyone help me to bypass it please, thanks in advanced
