Visualization
The default plot for each tensor is its directional magnitude, i.e. for each direction x it is plotted Q(x) = T_ijkl x_i x_j x_k x_l
setMTEXpref('defaultColorMap',blue2redColorMap);
C = stiffnessTensor.rand
plot(C,'complete','upper')
C = tensor (xyz)

set back the default color map.
setMTEXpref('defaultColorMap',WhiteJetColorMap)
There are more specialized visualization possibilities for specific tensors, e.g., for the elasticity tensor. See section Elasticity.
