IndexForm

• IndexForm[index] returns the string which will be used to format the generalized index (assumed not to have a minus in front).

• Default actions:
    - abstract indices are simply converted into a string
    - basis and component indices are colored according to the basis they belong to. Component indices are dealt with through the associated function CIndexForm.
    - directional indices are converted into the name of the vector, or into # when they are composite expressions.
    - labels are also converted into strings (after removing the LI head).
    - patterns are underlined.
• If changed, IndexForm must be manipulated with great care.
• See: Section 3.
• Last update: 28-X-2007 for version 0.9.3 of xTensor`.
