template<typename MAT >

number_traits<typename linalg_traits<MAT>::value_type>::magnitude_type gmm::condition_number	(	const MAT &	M,
		typename number_traits< typename linalg_traits< MAT >::value_type >::magnitude_type &	emin,
		typename number_traits< typename linalg_traits< MAT >::value_type >::magnitude_type &	emax
	)

computation of the condition number of dense matrices using SVD.

Uses symmetric_qr_algorithm => dense matrices only.

Parameters

M	a matrix.
emin	smallest (in magnitude) eigenvalue
emax	largest eigenvalue.
