List of all members.


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.


Public Types

typedef RandomAccessIterator x_iterator
 iterates over $ v_{ij} $ with $ j $ fixed.
typedef boost::reverse_iterator<
RandomAccessIterator > 
reverse_x_iterator
 iterates backwards over $ v_{ij} $ with $ j $ fixed.
typedef step_iterator< RandomAccessIterator > y_iterator
 iterates over $ v_{ij} $ with $ i $ fixed.
typedef boost::reverse_iterator<
y_iterator
reverse_y_iterator
 iterates backwards over $ v_{ij} $ with $ i $ fixed.
