class representing the lattice curvature tensor
The curvature tensor collects the spatial derivatives of the orientation field. In MTEX it is computed from an EBSD map or from a list of grains by the method curvature, and is the quantity the dislocationDensityTensor is derived from.
Since a two dimensional EBSD map gives no derivative in z direction, the third column of the tensor is NaN there.
Syntax
kappa = curvatureTensor(M,cs)Input
| M | 3x3 matrix |
| cs | crystal symmetry |
Output
| kappa | curvatureTensor |
Class Properties
| M | the tensor coefficients |
| rank | always 2 |
| CS | symmetry the coefficients refer to |
