Documentation

EinIndex is a one dimensional index and provides the normal way to interact with tensors. The identity of each object is used for deciding free indices and the summation indices. Note that a loop over an index which already is involved in a loop will be ignored. That is, current will not be affected by begin or next. To maintain correct loop status, it is important to break loops only when end is true.

EinIndex(int dim = 3)

Default yields a [0,2] index.
