SvdTraits Concept Reference

Definition

The concept SvdTraits describes the set of requirements to be fulfilled by any class used to instantiate the third template parameter of the class CGAL::Monge_via_jet_fitting<DataKernel,LocalKernel,SvdTraits>.

It describes the linear algebra types and algorithms needed by the class CGAL::Monge_via_jet_fitting.

Requirements

The scalar type, SvdTraits::FT, must be the same as that of the LocalKernel concept : LocalKernel::FT.

Has Models:

CGAL::Eigen_svd

FT SvdTraits::solve	(	const Matrix &	M,
		Vector &	B
	)

Solves the system \( MX=B\) (in the least square sense if \( M\) is not square) using a singular value decomposition and returns the condition number of \( M\).

The solution is stored in \( B\).
