Visualization
The default plot for each tensor is its directional magnitude, i.e. for each direction \(x\) we plot the quantity \(Q(x) = T_ijkl x_i x_j x_k x_l\)
set back the default color map.
There are more specialized visualization possibilities for specific tensors, e.g., for the elasticity tensor. See section Elasticity.
