I'm trying to use this piece of code to plot some slip planes and directions in cubic shapes, it works quite nicely. I did get an error (when plotting 111...

In your code, r is a 3x3 matrix, representing a stress tensor, which you later define as 'sigma'. If you apply the vector3d command on the 3x3 matrix, you get...

I think taking the angles between principle stress directions and slip plane/direction might be a bit too simplistic to calculate "partial" (?) Schmid factors. The Schmid factor should just be...

I'm pretty sure MTex already does what I suggested, but not totally sure. You can check the slipSystem/schmidFactor code in Mtex to see what it does when you input a...
