SpletThe vector z is the orthogonal projection of x onto the subspace S = range ( I - P) = null ( P) (By (6.2) [?]). From this z- xis orthogonal to S. We can write z- x as z- x = (I - P)x- x = x- Px- x = - Px. From this, we see z- x is the reflection of the image of x under P across z. Let y = (I - 2P)x= x- 2Px= x+ 2 (z- x). oh boy oh boy oh boy lyricsSpletSuch approximation is obtained by the truncated singular value decomposition (SVD) or, depending on the adopted regularizing term, by the truncated generalized SVD (GSVD). ...
