When
$AutoSymmetrizeCovDs
is False, symmetrizable covariant derivatives are not automatically symmetrized:
When
$AutoSymmetrizeCovDs
is True, symmetrizable covariant derivatives are automatically symmetrized:
Non-symmetrizable derivatives are not automatically symmetrized however:
When
$AutoSymmetrizeCovDs
is False, symmetrizable covariant derivatives are not automatically symmetrized:
