remove duplicate geometric objects, respecting their symmetry and tolerance.

Syntax

distinct = unique(x)

Description

For an MTEX object, unique(x, …) calls x.unique(…). Additional positional and keyword arguments are passed to that method unchanged. Its documentation specifies the accepted inputs, units, symmetry handling and optional outputs. Consult the corresponding method for the behaviour of a particular object type.

For numeric arrays without an MTEX method, this calls numpy.unique.

Signature

unique(x, *args, **kwargs)

Methods it calls

orientation	the disjoint list of orientations, symmetric equivalents within a tolerance taken as one
orthogonalTransform	the disjoint list of orthogonal transforms, those equal up to a tolerance taken as one
PoleFigure	the duplicated directions removed: equivalent specimen directions under the specimen group carry the same pole density, so they are merged and their intensities averaged
quaternion	the disjoint list of quaternions, those equal up to a tolerance in the coefficients taken as one
rotation	the disjoint list of quaternions, those equal up to a tolerance in the coefficients taken as one
SO3TangentVector	the disjoint list of tangent vectors at one shared reference
vector3d	the disjoint list of vectors, equal ones within a tolerance taken once

Used on

MisorientationTheory, ParentChildVariants
