Types

type Implementation

type Implementation struct{}

Implementation is the cgo-based C implementation of LAPACK routines.

func (Implementation) Dpotrf

func (impl Implementation) Dpotrf(ul blas.Uplo, n int, a []float64, lda int) (ok bool)

Dpotrf computes the cholesky decomposition of the symmetric positive definite matrix a. If ul == blas.Upper, then a is stored as an upper-triangular matrix, and a = U U^T is stored in place into a. If ul == blas.Lower, then a = L L^T is computed and stored in-place into a. If a is not positive definite, false is returned. This is the blocked version of the algorithm.
