A method of vector3d.

the Miller indices of a crystal direction in brackets, as text

Syntax

s = m.char()

{111}, where the frame has symmetry, else (111), [uvw].

s = m.char('uvw')

In another convention: ‘hkl’, ‘hkil’, ‘uvw’, ‘UVTW’.

s = m.char(family=False)

One plane or direction, (hkl) or [uvw].

s = m.char('LaTex')

As mathematics, a bar over the negative indices.

s = m.char(utf8=False)

A minus sign instead of the bar.

Description

A point group makes the indices stand for the whole symmetrically equivalent set, so they are written in the family brackets {hkl} and , while the trivial group leaves one plane or one direction, (hkl) and [uvw]. A direction outside a crystal frame is written in its coordinates, (1,2,3). A list of directions is written one after another. MATLAB's flags no_scopes and commasep are not taken.

Input

m vector3d, in a crystal frame for the indices

Keywords

keyword default description
style None the convention, ‘hkl’, ‘hkil’, ‘uvw’, ‘UVTW’ or ‘xyz’, or ‘LaTex’; by default the display’s
utf8 None a negative index as a digit with a bar over it rather than a minus sign; by default the preference ‘UTF8Output’
family None the family brackets {hkl} and ; by default where the frame has symmetry

Output

s str
