A method of spinTensor.

the rotation a spin tensor generates, the exponential of its axial vector, or the orientation a spin at a reference orientation leads to

Syntax

rot = W.exp()

The rotation of the spin.

ori = W.exp(ori0)

The orientation reached from ori0.

ori = W.exp(ori0, side='right')

The spin applied on the crystal side.

Description

A spin in a crystal frame acts on the right of the orientation, ori0 * exp(W), one in the specimen frame on the left, exp(W) * ori0, unless side says otherwise.

Input

W spinTensor

Keywords

keyword default description
ref None orientation, the reference the spin starts at, ori0 above
side None ‘left’ or ‘right’, the side the spin acts on; by default from the frame of W

Output

rot rotation, or orientation with a reference
