Detailed Description

Accessor for turning iteration over Diff2D into a mesh grid.

The mesh grid concept is adapted from MATLAB. It is a two banded image (i.e. with 2D vector pixel type) whose first band contains the x-coordinates of the current pixel, and whose second band contains the y-coordinates. See meshGrid() for more detailed documentation.

Member Typedef Documentation

◆ value_type

the value_type of a mesh grid is a 2D vector

Member Function Documentation

◆ operator()() [1/2]

value_type operator() ( ITERATOR const &  i) const

read the current data item

◆ operator()() [2/2]

value_type operator() ( ITERATOR const &  i,
DIFFERENCE const &  diff 
) const

read the data item at an offset (can be 1D or 2D or higher order difference).
