extend EBSD data to an grid

Description

matrix shaped regular grid. No interpolation is done hereby. Grid points in the regular grid that do not have a correspondence in the regular grid are set to NaN. Having the EBSD data in matrix form has several advantages:

  • required for gradient, curvature and GND computation
  • much faster visualization of big maps
  • much faster computation of the kernel average misorientation

Syntax

[ebsdGrid,newId] = gridify(ebsd)
[ebsdGrid,newId] = gridify(ebsd,'unitCell',unitCell)

Input

ebsd an EBSD data set with a non regular grid

Output

ebsd EBSDsquare, EBSDhex data on a regular grid
newId closest regular grid point for every non regular grid point

Options

extent extend of gridded map
unitCell unit cell of the gridded map

Example

mtexdata twins
ebsdMg = ebsd('Magnesium').gridify
plot(ebsdMg, ebsdMg.orientations)
ebsd = EBSD (y↑→x)
