Detailed Description

template<class RandomAccessIterator>
class QuantLib::LexicographicalView< RandomAccessIterator >

Lexicographical 2-D view of a contiguous set of data.

This view can be used to easily store a discretized 2-D function in an array to be used in a finite differences calculation.
