GOTolerance

GOTolerance

defines the maximal allowed deviation to regard two numerical values as equal.

Details and Options

  • After transformation of vectors containing numerical values slight deviations may occur. To compare such numerical results GOTolerance can be specified.
  • See: W. Hergert, M. Geilhufe, Group Theory in Solid State Physics and Photonics. Problem Solving with Mathematica

Examples

Basic Examples  (1)

First load the package:

Instal the group Oh.

Define the reciprocal lattice vectors.

To avoid a decrease of symmetry due to numerical issues, the transformed k-vectors are rounded with respect to GOTolerance.
