reduce ebsd data by a factor

Description

Keeps every fak-th site in both lattice directions. That sublattice is the same kind of lattice fak times coarser - square from a square grid, hexagonal from a hexagonal one - so the unit cell simply scales with fak.

Selecting on the lattice index (see lattice) rather than on positions or on matrix subscripts is what makes one implementation cover every case: a plain list and a gridded map, a square and a hexagonal grid, and a grid that is rotated or otherwise not axis aligned. EBSDhex used to override this with a version written on the staggered matrix subscripts, which could only ever express fak = 2 and rejected the second argument outright.

Syntax

ebsd = reduce(ebsd)   % take every second pixel horiz. and vert.
ebsd = reduce(ebsd,3) % take every third pixel horiz. and vert.

Input

ebsd EBSD
factor resample ebsd at rate factor (integer)

Output

ebsd EBSD
