A method of gbcAngle.

the connectivity of the pairs i[k], j[k]: the share of the angle levels their misorientation stays below, 0 across phases, 1 between not indexed measurements; a compiled loop when numba is the backend; MATLAB’s gbcAngle.evaluate

Syntax

c = gbcAngle(10*degree).evaluate(ebsd, i, j)

1 joined, 0 a boundary.

c = gbcAngle([10*degree, 2*degree]).evaluate(ebsd, i, j)

0.5 for a low angle boundary.

c = gbcAngle(10*degree).evaluate(ebsd, i, j, backend='numpy')

The NumPy loop.

Description

With a pair [high, low] the value is 1 below low, 0.5 between low and high and 0 above high: the share of the levels the misorientation angle stays below. calcGrains joins two pixels whose value is 1 into one grain.

Input

ebsd EBSD
i, j the flat indices of the pairs of measurements, equally long

Keywords

keyword default description
backend None ‘numba’ or ‘numpy’, by default the preference ‘kernels’

Output

c the connectivity of every pair, between 0 and 1
