PPT-Singular Value Decomposition(SVD)

Bo amp Shi Definition of SVD Formally the singular value decomposition of an mn real or complex matrix M is a factorization of the form where U is an mm real or complex unitary matrix Σ is an mn rectangular diagonal matrix with nonnegative real numbers on the diagonal and V the conjugate transpose of V is an . This is the 64257nal and best factorization of a matrix wher e is orthogonal is diagonal and is orthogonal In the decomoposition can be any matrix e know that if is symmetric positive de64257nite its eigenvectors ar e orthogonal and we can write T brPage 2br Intr oduction The singular alue decomposition SVD is just as amazing as the LU and QR decompositions It is closely related to the diagonal form of symmetric matrix What happens if the matrix is not symmetric It turns out that we can actor 6 De64257nition A ny r eal matrix can be decomposed uniquely as UDV is and column orthogonal its columns are eigen ve ctors of AA AA UDV VDU UD is and orthogonal its columns are eigen ve ctors of VDU UDV VD is diagonal nonne ga ti ve r eal v alues ca Miguel Goenaga (Presenter).
