Invariant — Invariants of vectors and tensors.


Subclasses are listed as they appear in the GUI and (in parentheses) as they appear in scripts.


Objects of the Invariant class are used by various Output classes to determine what quantity to compute. Invariants are quantities, such as the magnitude of a vector or the determinate of a tensor, that don't depend on a choice of coordinate system.
