log

(method of orientation)

the misorientation vector in crystal coordinates

Description

Mathematically, misorientation vector is the the inverse of the exponential map, hence the name log.

Syntax

v = log(ori)
% the misorientation vector in crystal coordinats
v = log(ori,ori_ref)
% the misorientation vector in specimen coordinats
r = ori_ref .* v

Input

ori

orientation

ori_ref

orientation

Output

v
