LieD

• LieD[v][expr] represents the Lie derivative of expr along the contravariant vector field v.
• LieD[v, covd][expr] computes the Lie derivative of expr using the covariant derivative covd.

• The free index of v is assumed to be an ultraindex.
• See: Section 4.8.
• See also: LieDToCovD.
• New in version 0.
• Last update: 25-X-2007 for version 0.9.3 of xTensor`.
