WeightedWithBasis

• WeightedWithBasis is an option for DefCovD to extend a Levi-Civita connection on densities in a given basis.
• WeightedWithBasis[covd] returns the basis along which the Levi-Civita connection covd has been extended, or Null otherwise.

• This option is typically used through DefMetric.
• The basis can be AIndex as special case.
• The default value for both the option and function is Null.
• See: Section 4.4.
• See also: DefCovD, WeightOf, WeightOfTensor.
• New in version 0.
• Last update: 16-V-2008 for version 0.9.5 of xTensor`.
