SpletFurthermore, since u ∈ KerA,wehaveAu =0,and thus Ax = p iﬀ Av = p,whichshowsthatthesolutions of Ax = p for which x has minimum norm must belong to (KerA)⊥. However, the restriction of A to (KerA)⊥ is injective. This shows that there is a unique x of minimum norm minimizing#Ax −b#2,andthatitmustbelongto(KerA)⊥. SpletThe rank of a matrix tells you how many solutions there are to Ax=0. The reduced row-echelon form of the matrix tells you what those solutions are.

SpletSVD is usually described for the factorization of a 2D matrix A . The higher-dimensional case will be discussed below. In the 2D case, SVD is written as A = U S V H, where A = a, U = u , S = n p. d i a g ( s) and V H = v h. The 1D array s contains the singular values of a and u and vh are unitary.

SpletThe SVD and Solving Ax = b The SVD is how Matlab solves the system of equations for the least squares solution.
