Description

Given an EBSD the orientations on either side of a segment are looked up through gB.ebsdId, which is only meaningful while every segment still runs between one specific pair of pixels. smoothBoundary breaks that by default - it merges and resamples segments - so smooth with 'noSimplify','noRefine' before calling this, or pass the grain2d instead and work from the grain mean orientations.

Syntax

gbnd = calcGBND(gB,ebsd)

From the orientations of the pixels.

gbnd = calcGBND(gB,grains)

From the grain mean orientations.

gbcd = calcGBND(gB,grains,mori)

The gbcd for a specific misorientation.

gbnd = calcGBND(gB,ebsd,'halfwidth',10*degree)

Use a specific halfwidth.

Input

`gB`	`grainBoundary`
`ebsd`	`EBSD`
`grains`	`grain2d`
`mori`	`misorientation or orientation relationship`
`odf`	`SO3Fun used for texture correction`

Options

`halfwidth`	`used for kernel density estimation`
`nonneg`	`use a nonnegative kernel`

Output

gbnd S2FunHarmonic
