CommutePDs

• CommutePDs is a Boolean option for SymmetryOf (and indirectly of ToCanonical and Simplification) that specifies whether PD derivatives must be commuted or not in the construction of the symmetry of an expression. This has important consequences in the canonicalization of that expression.

• The default value for the option is True.
• See: Section 4.5, Section 7.1.
• See also: PD,  ToCanonical.
• New in version 0.
• Last update: 27-X-2007 for version 0.9.3 of xTensor`.
