WeightOfTensor

• WeightOfTensor[tensor] gives the weight of tensor as a tensorial density.
• WeightOfTensor is an option for DefTensor giving the weight of the defined tensor.

• Each tensorial density has an upvalue for this function. In all other cases the default setting 0 for this function is used.
• A weight is always a linear combination of names of bases. It is 0 if tensor is not a density.
• See: Section 4.4.
• See also: DefTensor, WeightOf, WeightedWithBasis.
• New in version 0.
• Last update: 16-V-2008 for version 0.9.5 of xTensor`.
