Description

matrix shaped regular grid. No interpolation is done herby. 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 visualisation 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 = EBSDsquare (y↓→x, row↓→col)
