Detailed Description

template<typename T>
class cvr::internal::luDecompositionLapackInterface< T >

Offers a direct interface to the LAPACK function getrf for computing an LU decomposition with partial pivoting.

This function is needed by other classes that use it as part of the LAPACK processing chain.

Member Function Documentation

template<typename T>

int cvr::internal::luDecompositionLapackInterface< T >::getrf	(	integer *	rows,
		integer *	cols,
		T *	a,
		integer *	lda,
		integer *	ipiv,
		integer *	info
	)			const

GETRF computes an LU factorization of a general M-by-N matrix A using partial pivoting with row interchanges.

The factorization has the form

     A = P * L * U

where P is a permutation matrix, L is lower triangular with unit diagonal elements (lower trapezoidal if m > n), and U is upper triangular (upper trapezoidal if m < n).
