Detailed Description

An adaptor that converts a vnl_sparse_matrix<T> to a vnl_linear_system

Constructor & Destructor Documentation

template<class T >

vnl_sparse_matrix_linear_system< T >::vnl_sparse_matrix_linear_system	(	vnl_sparse_matrix< T > const &	A,
		vnl_vector< T > const &	b
	)		`[inline]`

:Constructor from vnl_sparse_matrix<double> for system Ax = b.

Keeps a reference to the original sparse matrix A and vector b so DO NOT DELETE THEM!!
