## Public Types

typedef unspecified_type FT
The field number type; must be a model of the concept FieldNumberType

typedef CGAL::Aff_transformation_3< K > Aff_transformation_3
The 3D affine transformation type; the template parameter K must be a model of Kernel and be compatible with the type Point_3

typedef unspecified_type Matrix
A 3x3 matrix type; model of the concept SvdTraits::Matrix and which supports matrix-matrix and scalar-matrix multiplication, as well as matrix-matrix addition.

typedef unspecified_type Vector
A 3 dimensional vector type; model of the concept SvdTraits::Vector and which supports matrix-vector and multiplication.
