DependenciesOf

• DependenciesOf[expr] gives the list of parameters and manifolds upon which expr depends.

• Indices of types B, C can have dependencies, stored as upvalues of the corresponding basis for the function xCoba`DependenciesOfBasis.
• Indices of type D can have dependencies: those of its expression.
• The dependencies of a tensor expression are those of the tensor itself (DependenciesOfTensor) and those of its indices.
• Covariant derivatives are assumed not to add dependencies, apart from those of its index.
• DependenciesOf acting on unknown expressions returns the symbol AnyDependencies.
• See: Section 4.4.
• See also: ManifoldsOf, ParametersOf.
• New in version 0.
• Last update: 23-IX-2007 for version 0.9.3 of xTensor`.
