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

typedef TinyVector<Diff2D::MoveX, 2> value_type

the value_type of a mesh grid is a 2D vector

(

ITERATOR const &

i

)

const

read the current data item

operator()() [2/2]
