Consistent Miller Indices dispStyle

[ralfHielscher]

@jhiscocks, please provide some more information what you would like to have changed in Miller/dispStyle

• what are the specific use cases that do not work with the current notation
• how would you like to see this fixed
• have a look at #529 where I started working on this.

Ralf.

Hi Ralf, I realised I hadn't explained things clearly so I apologize for that. If you look at the Miller function documentation

dispStyle - 'hkl', 'uvw', 'HKIL', 'UVTW'

except, when you try to use 'HKIL' it doesn't work correctly. Enter the following (although it's trivial, the displayed output changes between them).

m1=Miller(1,1,-2,3,cs,'UVTW') 
m2=Miller(1,1,-2,3,cs,'HKIL')

figure;plot(m1,'upper','labeled')
figure;plot(m2,'upper','labeled')

I get an error message after the second one of these, but if you use m2=Miller(1,1,-2,3,cs,'hkil') it works as expected. Am I missing something here?

Hi Jessica,

I see the inconsistency. My problem is a little bit that for uvw and UVTW we have in general u != U . That is why we have u and U. For HKIL and hkl we have always h=H, k = K and l = L.

But I think you are right, we should make it more strict.

could you please download

and check whether this is better for you.

Ralf.

Hi Jessica,

I have reworked the hkl / uvw management in the current beta. Would you like to test it?

Ralf.

Hi Ralf, I finally got around to checking this out with version 5.5.2, and the HKIL thing works as I would expect now, so that's fixed.
