What is SVD(singular value decomposition) SVD can be understood from a geometric sense for square matrices as a transformation on a vector. Consider a square n x n matrix M multiplying a vector v to produce an output vector w: w = M*v The singular value decomposition M is the product of three matrices M=U*S*V, so w=U*S*V*v. U and V are orthonormal matrices.
