Public Attributes | |
std::size_t | flat |
Index into the flattened 2-d function. | |
std::size_t | nx |

std::size_t | ny |

A custom tuple that relates the indices of two 1-d functions for x and y to the flattened index for the 2-d function they form.
The packing algorithm is not specified by Index2d itself; it is intended to be a common data structure for other classes that define possibly different algorithms (e.g. PackedIndexIterator).
