Plot pole figure from matlab vectors / matrix

[Rémy Bretin]

Hi,

I have a matrix of euler angles on matlab such as :
EA=[ phi1_1 Phi_1 phi2_1;

         phi1_2 Phi_2 phi2_2;

         phi1_3 Phi_3 phi2_3;

         phi1_4 Phi_4 phi2_4];

And for each orientation, I have an associated value :

V=[V_1;

      V_2;

      V_3;

      V_4];

I would like to know first how to plot those values with a colormap on a pole figure (or inverse pole figure) and then how to reduce it to the symmetry triangle in the case of a cubic structure.

I thank you in advance,

Rémy

Hi Remy,
just define an orientation (have a look at help orientation/orientation) - assuming you also have a crystalSymmetry (see help crystalSymmetry), define a crystal direction (have a look at help Miller) to plot pole figures using plotPDF or define a vector3d (have a look at help vector3d) to plot inverse pole figures with plotIPDF. Second argument for plotPDF or plotIPDF (help orientation/plotIPDF and help orientation/plotPDF) is interpreted as the property used for colorcoding points.

For example:
cs=crystalSymmetry('432')
o = orientation('Euler',EA*degree,cs)
plotIPDF(o,V,vector3d(1,2,3))

Hope this helps.
Cheers,
Rüdiger

Thank you a lot for the fast and right answer. It works! :)

Now I have a new problem: how do I add a latex title to the colorbar? And how do I add a 90° rotation to the title too?

mtexColorbar('title','\boldmath$\Delta\varepsilon^{A^{eff}}_{B~33}$','Interpreter','latex') doesn,t work :/

Thanks again,

Rémy

Good Morning,
this is some sort of bug because if you use \epsilon it works.

Here's a workaround for now:

cb = mtexColorbar;
cb.Label.Interpreter ='latex'
cb.Label.String='\boldmath$\Delta\varepsilon^{A^{eff}}_{B~33}$'
