template<class T>

template<class MAT >

void gmm::SuperLU_factor< T >::build_with	(	const MAT &	A,
		int	permc_spec = `3`
	)

inline

Do the factorization of the supplied sparse matrix.

template<class T>

template<typename VECTX , typename VECTB >

void gmm::SuperLU_factor< T >::solve	(	const VECTX &	X,
		const VECTB &	B,
		int	transp = `LU_NOTRANSP`
	)		const

inline

After factorization, do the triangular solves.

transp = LU_NOTRANSP -> solves Ax = B transp = LU_TRANSP -> solves A'x = B transp = LU_CONJUGATED -> solves conj(A)X = B
