In numerical recipes is routine for it but if we want to write it from scratch i found reduction to Hessenberg by Gaussian elimination (Householder reflections would be better but I havent found how to effectively multiply matrix by Householder reflections) I derived multiplication by rotation matrices G from the left and G^{T} from the right which allowed to write QR decomposition But which shifts should I use How to use deflation QR metod can be done in place but how to do it
Such a useful as a physics student studying inversion problem, It likes drop from heaven
In numerical recipes is routine for it
but if we want to write it from scratch
i found reduction to Hessenberg by Gaussian elimination
(Householder reflections would be better but I havent found how to effectively multiply matrix by Householder reflections)
I derived multiplication by rotation matrices G from the left and G^{T} from the right
which allowed to write QR decomposition
But which shifts should I use How to use deflation
QR metod can be done in place but how to do it
Pretty good video, friendo! Thanks!
Can you write program for eigenvalues based on this video only
if yes then indeed it is good video
very nice!
Thanks!
