TensorWrapper

TensorWrapper[expr]
wraps all tensorial terms in expr in the inert head TensorWrapper.

MORE INFORMATION

TensorWrapper is a special inert head chiefly used for CollectTensors.

TensorWrapper threads over lists, sums, and equations.

Constant terms in expr are left out of the TensorWrapper head.

For consistency reasons, TensorWrapper[constant] gives constant*TensorWrapper[UnitConstant].

The color of the printed parantheses of TensorWrapper can be set with $TensorWrapperColor.
