Product with L or transpose of L for a Cholesky factorization [ Reply ]
By: Marc Durufle on 2015-09-16 14:24
I enjoyed the possibility of solving by L or the transpose of L when a Cholesky factorization is performed. I would like to know if it was possible to perform the multiplication by L (and the transpose). Indeed, when an eigenvalue problem is solved by shifting the spectrum (the spectrum of (M - sigma K)^{-1} is computed), the needed operation is the multiplication by L.
Best regards.
