the reference frame glued to the lattice basis of a phase

The basis are the crystal axes a, b, c in canonical Euclidean coordinates, with their lengths - the X||a*, Z||c alignment choice belongs to this frame, not to the point group. A crystal frame can be defined directly by the lattice parameters and alignment options, without any symmetry involved.

Syntax

cF = crystalFrame(axes)
cF = crystalFrame(axes,'name','Forsterite')
% by lattice parameters and alignment, the default is X||a*, Z||c
cF = crystalFrame([1 2 3],[70 80 120]*degree,'Z||a*')
cF = crystalFrame([3 3 5],'X||a')

Input

axes 1x3 vector3d, the crystal axes a, b, c
abc length of the crystal axes
abg angles between the crystal axes alpha, beta, gamma

Options

X||a, X||a*, Z||c, ... alignment of the Cartesian axes
EDAX vendor alignment convention of EDAX / TSL / OIM
pointId point group id, for the lattice consistency checks

Dependent Class Properties

abc length of the crystal axes
abg angles between the crystal axes
alpha angle between b and c
beta angle between c and a
gamma angle between a and b
