    abstract     = {Summary: Abstract recent work has outlined a framework for analyzing diffusion tensor gradient and covariance tensors in terms of invariant gradient and rotation tangents, which span local variations in tensor shape and orientation, respectively. This chapter hopes to increase the adoption of this framework by giving it a more intuitive conceptual description, as well as providing practical advice for its numeric implementation. Example applications are described, with an emphasis on decomposing the third-order gradient of a diffusion tensor field.},
